Executive Summary

On the night of May 18, 2023, Raymond Mattia -- a 58-year-old member of the Tohono O'odham Nation, traditional singer, artist, sculptor, hunter, prospector, community council member, and lifelong resident of Menagers Dam Village on the U.S.-Mexico border in southern Arizona -- was shot and killed by three U.S. Border Patrol agents in front of his own home. He had called law enforcement himself, earlier that evening, to report border-crossers on his property. When agents arrived and surrounded him at his doorstep, Mattia cooperated: he threw down a sheathed knife when instructed, raised his hands when told to. Body camera footage shows that 31 seconds elapsed between the first command and the first shot. In those 31 seconds, agents issued multiple conflicting commands -- "keep your hands up," "put it down," "get on your fucking face," "put your hands out of your fucking pocket" -- while Mattia attempted to comply. When he pulled his right hand from his jacket pocket, revealing a dark object, at least three agents opened fire. The dark object was his cellphone. He was unarmed.

Approximately 38 rounds were fired at Raymond Mattia at his doorstep. An autopsy ruled his death a homicide and found he was struck nine times -- in his torso, back, abdomen, shoulder, buttock, forearm, elbow, and both thighs. A toxicology report showed methamphetamine, alcohol (BAC 0.185%), amphetamine, and oxycodone in his system -- a finding the government would emphasize, but which has no bearing on whether shooting an unarmed man complying with commands is justified.

In October 2023, the U.S. Department of Justice declined to file criminal charges against the agents, stating the use of force "does not rise to the level of a federal criminal civil rights violation." The Tohono O'odham Nation's Chairman and Vice Chairwoman called this "a travesty of justice" and said they "cannot and will not accept" the decision. The agents -- identified in December 2024 as Scott Whitehouse, Dan Sifuentes, and Ivan Torralva -- remained unnamed by the government for over 18 months, identified only through a civil lawsuit filed by Mattia's family. As of late 2025, the wrongful death lawsuit is partially stayed while the Ninth Circuit Court of Appeals considers the agents' qualified immunity defense. The agents are seeking to avoid not only trial but discovery itself.

Raymond Mattia's killing is not an isolated incident. It is the product of decades of border militarization on the Tohono O'odham Nation -- 2.8 million acres of sovereign indigenous land bisected by 62 miles of international border -- where over 2,000 Border Patrol agents operate on tribal territory, conducting surveillance, vehicle stops, and armed patrols in indigenous communities. Since Mattia's death, residents of Menagers Dam have said they will no longer call Border Patrol or tribal police for help. The man who called for help was killed by the people he called.


1. VICTIM PROFILE

Raymond Mattia

Personal Information:
- Full Name: Raymond Mattia
- Age: 58 years old
- Citizenship: U.S. citizen
- Tribal Affiliation: Tohono O'odham Nation (enrolled member)
- Residence: Menagers Dam Village (Ali Chuk), Tohono O'odham Nation, approximately 140 miles southwest of Tucson and roughly one mile from the U.S.-Mexico border
- Lifelong Resident: Spent his entire life in Menagers Dam
- Family: Sister Annette Mattia lived in adjacent home; niece Yvonne Nevarez; described as uncle, brother, nephew, cousin to many; great-great uncle to children in the family
- Daughter: Was bringing him a birthday cake the night he was killed

Who Raymond Mattia Was:

Raymond Mattia was deeply embedded in his community and his culture. He was a traditional singer for the Tohono O'odham -- a role of significant cultural importance -- and would sing all night during the traditional ceremonies held in his community. He was an artist, a sculptor, a hunter, and a prospector.

He served on the local tribal community council for Menagers Dam Village, where he was known as a community advocate. Ophelia Rivas, a Tohono O'odham elder who lived just a few houses down from Mattia, described him as well-known and a friend. He would "often speak up about Border Patrol abuses" in his community.

In earlier years, Mattia had campaigned publicly against the negative influence of drug smugglers who passed through his community. He also worked to connect Native American people in substance-abuse treatment with their heritage -- using cultural knowledge and traditional practices to help his people heal.

His niece Yvonne Nevarez said Mattia's family was large and close-knit: "He is an uncle, a brother, a nephew, a cousin to many, and a great-great uncle to my children."

The Cruel Irony:
Mattia had a documented history of calling law enforcement to report activity on his property. The night he was killed, he had done exactly what residents of a border community are told to do: he called for help. He was killed by the people he called.


2. THE TOHONO O'ODHAM NATION: CONTEXT

A Nation Divided by a Border

The Tohono O'odham people have lived on their ancestral lands for over a thousand years. Their traditional territory stretches from the Gila River in present-day Arizona south to the Sea of Cortez in northern Mexico. The Gadsden Purchase of 1853 -- without consultation or consent from the indigenous inhabitants -- imposed an international boundary through the middle of this unified territory, separating families, communities, and sacred places.

Key Facts:
- Size: 2.8 million acres (second-largest reservation in the U.S.)
- Border frontage: 62 miles of U.S.-Mexico international boundary
- Membership: ~34,000 members, including over 2,000 in Mexico
- Location: Southwestern Arizona, the Sonoran Desert

The Occupation

Since 9/11, the Tohono O'odham Nation has experienced what its leaders have described as a military occupation:

  • Pre-9/11: The border through O'odham land was relatively open; tribal members crossed freely along traditional paths to visit family, attend ceremonies, and maintain cultural connections
  • Post-9/11 Patriot Act: Crossing was restricted to three "tribal gates" -- CBP-managed checkpoints requiring documentation. Traditional paths were made illegal. Drones, motion sensors, surveillance cameras, and vehicle barriers appeared across the landscape, including near burial grounds and in ancient saguaro forests sacred to the O'odham

Scale of Militarization:
- The Tohono O'odham Nation has been called "the most militarized community in the United States"
- Israeli company Elbit Systems contracted to build integrated fixed surveillance towers on tribal land
- Border Patrol agents conduct routine vehicle stops, tailing, and in some cases have entered homes without warrants
- The Nation spends approximately $3 million of its own money annually on border security -- never reimbursed by the federal government
- The tribal police department spends more than a third of its time on border-related issues
- Chairman Edward Manuel testified at a UN hearing on indigenous rights that when he returned to the Nation after six years away, it had become "a military state"

Documented Abuses:
- 2002: Border Patrol agent ran over and killed a Tohono O'odham teenager
- 2014: Border Patrol agent shot and injured two Tohono O'odham men after their truck sideswiped his vehicle
- 2009-2012: 809 complaints filed against Border Patrol; only 13 resulted in disciplinary action; many complainants were never notified whether their complaint was investigated
- Ongoing reports of agents pulling people from vehicles, pepper-spraying tribal members, hitting them with batons
- Tribal members routinely harassed and treated as undocumented migrants on their own sovereign land

Destruction of Sacred Sites:
- Quitobaquito Springs and Monument Hill -- sites sacred to the Tohono O'odham, including burial grounds -- were bulldozed and blasted by CBP contractors for border wall construction
- National Park Service recognized the burial sites exist; CBP contractors proceeded anyway

Tohono O'odham Response:
- Over 20 resolutions opposing border fencing passed over the past two decades
- The Nation fully recognizes the need for border security but insists on sovereignty and consultation
- The Nation has actively used indigenous sovereignty to resist border militarization

Why This Context Matters

Raymond Mattia was not killed in a vacuum. He lived in a community that has experienced decades of militarized occupation of its sovereign land. Border Patrol agents operate on the Nation as if it were federal territory, not sovereign indigenous land. The shooting of a tribal member at his own doorstep is the extreme expression of an occupation that has been eroding O'odham sovereignty, culture, and safety for over two decades.


3. INCIDENT TIMELINE

May 18, 2023 - The Night of the Killing

Pre-Incident:
- Earlier in the evening, Mattia exchanged text messages with his sister reporting that three men -- presumed border-crossers -- had been in his home demanding to use his phone
- The confrontation was apparently tense; Mattia grabbed a hunting knife (or machete) to run the men off
- Mattia told his sister he called authorities to report the incident
- A 911 call about "shots fired" was placed from the Menagers Dam area

Border Patrol Response:
- The Tohono O'odham Nation Police Department (TOPD), which had one officer in the area, requested assistance from Border Patrol
- Three Border Patrol agents from the Tucson Sector Ajo Station responded
- The response was to a "shots fired" call

9:39 PM - The Encounter:
Body camera footage captured by cameras worn by the three CBP agents shows:

  1. Mattia emerges from his home -- He is seen standing outside his front door, approximately two feet from it
  2. Tribal police officer speaks with Mattia -- A TOPD officer tells Mattia to "put his hands above his head"; Mattia responds, "I am"
  3. Mattia throws down his knife -- He tosses a sheathed knife (or machete) several feet away from the police officer, as instructed
  4. Conflicting commands begin -- Within five seconds of Mattia's compliance:
  5. One CBP agent tells him to keep his hands up
  6. Another orders him to "Put it down for me"
  7. Another screams: "Get on your fucking face!"
  8. Another yells: "Put your hands out of your fucking pocket!"
  9. Mattia attempts to comply -- He raises his right hand from his jacket pocket
  10. The cellphone -- His hand holds a dark object: his cellphone

31 Seconds -- That is the total elapsed time from the first command to the first shot.

The Shooting:
- At least three agents (Whitehouse, Sifuentes, Torralva) opened fire simultaneously
- Approximately 38 rounds fired
- Mattia collapsed face-first on the ground immediately
- He was approximately two feet from his front door

Immediately After:
- Body camera footage shows agents repeatedly asking: "Did anyone find a firearm?"
- No firearm was found
- Agents moved in to handcuff Mattia (who was dying or already dead)
- A cellphone and black phone case were visible on the ground near Mattia

Mattia died shortly after the shooting.

Sister's Account

Annette Mattia heard the gunshots from her adjacent home. She has described ongoing trauma and anxiety around Border Patrol presence since that night.


4. THE AGENTS

Identification

For over 18 months, the U.S. government refused to identify the agents who fired. They were listed as "John Does" in the initial lawsuit. In December 2024, the family's attorneys identified them through the discovery process and filed an amended complaint naming:

  1. Scott Whitehouse -- Border Patrol Agent, Tucson Sector Ajo Station
  2. Dan Sifuentes -- Border Patrol Agent, Tucson Sector Ajo Station
  3. Ivan Torralva -- Border Patrol Agent, Tucson Sector Ajo Station

Attorneys Ryan Stitt and Marcus Bourassa issued a summons for the three agents, who they said "shot and killed Raymond for no reason." "Despite the lack of a threat and his compliance, at least three of the agents met his compliant calm demeanor with a hail of gunfire," the attorneys wrote.

Government Response to Identification:
- CBP said it does not comment on pending litigation
- No public statement on the agents' current status or any disciplinary action


5. AUTOPSY AND FORENSIC FINDINGS

Medical Examiner's Report

Manner of Death: HOMICIDE (ruling has no bearing on criminal charges; it is a medical classification meaning "death caused by another person")

Cause of Death: Gunshot wounds

Gunshot Wounds (9 total):
- Torso
- Back (shot in the back)
- Abdomen
- Shoulder
- Buttock
- Forearm
- Elbow
- Right thigh
- Left thigh

Rounds Fired: Approximately 38 (initial reports); body camera footage and ballistic analysis confirmed the volume of fire

Toxicology:
- Blood alcohol content: 0.185% (more than twice the legal driving limit)
- Methamphetamine detected
- Amphetamine detected
- Oxycodone detected

Analysis of Toxicology:
The toxicology findings have been cited by the government in its defense. However:
- Intoxication does not negate a person's right to not be shot while unarmed and complying with commands
- Mattia was at his own home, on his own sovereign tribal land
- Body camera footage shows him conversing and responding to commands -- his intoxication did not prevent comprehension or compliance
- He successfully threw down his knife when instructed to do so
- The decision to fire was based on agents mistaking his cellphone for a weapon -- not on his sobriety

Physical Evidence

  • No firearm found on or near Mattia
  • A sheathed knife/machete -- thrown down before the shooting -- found feet away
  • A cellphone and black phone case found on the ground near Mattia's body
  • The cellphone was the "dark object" agents mistook for a weapon

6. BODY CAMERA FOOTAGE

Release and Content

Released: June 2023, by U.S. Customs and Border Protection
Format: 23-minute edited video from cameras worn by three agents

Key Footage:
- Agents moving through the dark property
- Mattia standing outside his front door, conversing with TOPD officer
- Mattia complying: responding to commands, throwing down knife
- Rapid escalation: conflicting commands from multiple agents simultaneously
- Mattia pulling hand from pocket (holding cellphone)
- Fusillade of approximately 38 rounds
- Mattia collapsing face-first
- Agents asking repeatedly whether anyone found a firearm
- Cellphone visible on the ground

Expert Reaction:
Frank Figliuzzi, former FBI civil rights supervisor (NBC News contributor), said the video shows agents made a mistake in thinking the cellphone was a firearm. He acknowledged it would likely be "deemed a justified use of force" given the "shots fired" call context, darkness, and the way Mattia pulled out his phone -- but noted it was unmistakably a mistake.


Criminal Investigation

Investigating Bodies:
- FBI
- CBP Office of Professional Responsibility
- U.S. Attorney's Office for the District of Arizona

Decision: DECLINED to file charges (October 2023)

Reasoning: "The agents' use of force under the facts and circumstances presented in this case does not rise to the level of a federal criminal civil rights violation or a criminal violation assimilated under Arizona law"

Tribal Nation Response:
- Chairman Verlon M. Jose and Vice Chairwoman Carla L. Johnson issued joint statement
- Called the decision "a travesty of justice"
- "Cannot and will not accept the U.S. Attorney's decision"
- The tribe organized formal protests against the decision

Civil Lawsuit

Filed: November 2023 (notice of $15 million tort claim); May 2024 (formal wrongful death suit)

Claims (8 total):
1. Excessive use of force (Bivens claim -- constitutional violation)
2. Denial of familial association (constitutional violation)
3. Negligence (Arizona tort law)
4. Wrongful death (Arizona tort law)
5. Assault (Arizona tort law)
6. Battery (Arizona tort law)
7. Additional claims under Bivens and the Federal Tort Claims Act

Damages Sought: $15 million

Attorneys for the Family:
- Ryan Stitt
- Marcus Bourassa

Government's Defense (filed early 2025):
- Assistant U.S. Attorney Gabriel Peraza argued the family "failed to make a claim under federal law"
- Argued the claims should be dismissed because the Supreme Court had "foreclosed implied constitutional claims against any Border Patrol agent" (citing Egbert v. Boule, 2022)
- Sought not just dismissal but to avoid discovery entirely

Federal Judge's Ruling (August 2025)

Judge: U.S. District Judge Rosemary Marquez (Tucson)

Decision: Allowed the case to partially move forward
- Some claims survived the government's motion to dismiss
- Federal Tort Claims Act claims against the U.S. government may proceed

Qualified Immunity Appeal (December 2025)

Current Status: Case partially stayed
- The three named agents appealed to the Ninth Circuit Court of Appeals, seeking qualified immunity
- Judge Marquez agreed to partially stay the lawsuit while the appeal is considered
- The stay applies to claims against the individual agents
- Claims against the U.S. government under FTCA may continue

Family's Response:
- Attorney Bourassa called the qualified immunity questions "frivolous"
- Argued the agents were seeking "to not only postpone the trial, but to avoid discovery altogether"
- Noted: "As his killers, the individual defendants will have to participate in discovery about Raymond Mattia's shooting regardless of whether they prevail in their appeal"


8. COMMUNITY IMPACT

Menagers Dam Village After the Killing

The shooting of Raymond Mattia at his own doorstep has fundamentally altered the relationship between the community and law enforcement:

  • Residents say they will no longer call Border Patrol or tribal police for help -- this is a direct and documented consequence of the killing
  • The involvement of a Tohono O'odham Police Department officer strained the relationship between tribal police and the approximately 28,000 Nation members, especially in Menagers Dam (about 96 miles southwest of Tucson)
  • Cousin Joanna Mattia: "I drive by the Border Patrol station and wonder if the agents who killed my cousin are still there"
  • Niece Yvonne Nevarez: "An unjustified murder"
  • Sister Annette Mattia: Ongoing trauma and anxiety around Border Patrol presence

What Was Lost:
On what would have been Mattia's 59th birthday, family members spoke publicly. They said they no longer feel safe in their own community. The very act that Mattia performed -- calling for help when border-crossers entered his home -- is now something community members are afraid to do. The killing has taught Menagers Dam residents that seeking help from law enforcement can get you killed.

Tribal Government Response

The Tohono O'odham Nation's executive office:
- Called the DOJ's decision not to charge "a travesty of justice"
- Organized formal protests
- Connected the shooting to the broader pattern of Border Patrol militarization and abuse
- Reaffirmed the Nation's sovereignty position
- Supported the family's pursuit of civil justice


9. PATTERN ANALYSIS

Border Patrol Use of Force Against Indigenous People

Mattia's killing is the most extreme in a documented pattern:
- 2002: Agent ran over and killed a Tohono O'odham teenager
- 2014: Agent shot and injured two Tohono O'odham men
- 809 complaints (2009-2012) with 13 resulting in discipline
- Routine harassment: tailing, vehicle stops, pepper spray, baton use, warrantless home entries

The "Shots Fired" Response Escalation

Agents responded to a "shots fired" call. This context is used to justify the level of force. But:
- The "shots fired" in question may have been Mattia himself, firing to scare off the border-crossers who invaded his home
- When agents arrived, Mattia was cooperating, not shooting
- He had already thrown down his knife
- He was obeying commands
- 31 seconds is not a measured, professional response -- it is a panicked, militarized reaction

Conflicting Commands as Death Sentence

The body camera footage reveals that agents issued multiple simultaneous, contradictory orders:
- "Keep your hands up"
- "Put it down"
- "Get on your fucking face"
- "Put your hands out of your fucking pocket"

This created an impossible compliance situation. No matter what Mattia did -- keeping his hands up, reaching down, getting on the ground -- he would be disobeying at least one command. When he attempted to pull his hand from his pocket (following one set of commands), agents perceived the movement as threatening and fired. This is a recognized problem in use-of-force training literature: conflicting commands from multiple officers create situations where compliance is physically impossible, and any movement can be interpreted as a threat.

Cellphone Mistaken for Weapon

This is a recurring pattern in law enforcement killings:
- Agents mistake dark objects (phones, wallets, keys) for weapons
- They fire based on assumption rather than confirmed visual identification
- The "shots fired" context primes agents to expect a gun
- Low-light conditions exacerbate the problem
- As Mattia's niece stated: "Now anyone with a cell phone in their pocket can be justifiably shot and killed if the officers involved assume you have a weapon"

38 Rounds at a Man 2 Feet from His Door

The volume of fire -- approximately 38 rounds -- is itself evidence of excessive force. Nine rounds struck Mattia. He was shot in the back, indicating he had turned or was falling when at least some rounds were fired. Three agents firing simultaneously for several seconds into a man at his doorstep, who had just thrown down his knife and raised his hands, represents a catastrophic failure of proportionality.

The Government Refused to Name the Agents for 18 Months

The agents' identities were concealed for over a year and a half. They were only identified through civil discovery. This pattern -- where the government protects the identities of agents who kill -- makes public accountability impossible and signals to agents that their actions will be shielded.

Toxicology as Posthumous Character Assassination

Releasing the toxicology report -- showing alcohol, methamphetamine, and opioids -- served the narrative that Mattia was "not a sympathetic victim." This is a documented pattern in police shootings: toxicology and criminal history are used to retroactively justify the killing, distracting from the central question of whether the use of force was proportionate and lawful. Mattia was at his own home. He was not driving. He was not threatening anyone. His sobriety is irrelevant to whether firing 38 rounds at an unarmed, compliant man is justified.

Qualified Immunity: The Architecture of Impunity

The agents are currently seeking qualified immunity -- a legal doctrine that shields government officials from civil liability unless they violated "clearly established" rights. The agents' argument is essentially: because no court has previously ruled that firing 38 rounds at a person holding a cellphone under these specific circumstances violates the Constitution, they cannot be held liable. This creates a circular logic where rights are never "clearly established" because officials are always shielded before a court can rule on the merits.


10. CRITICAL QUESTIONS

  1. Why did three agents fire approximately 38 rounds at a man who had just thrown down his knife and raised his hands?
  2. Why were conflicting commands issued simultaneously, creating an impossible compliance situation?
  3. Did any agent positively identify a weapon before firing, or did all three fire based on assumption?
  4. Why was Mattia shot in the back if he was facing the agents and raising his hands?
  5. What training did these agents receive on interacting with tribal members on sovereign indigenous land?
  6. Why were the agents' identities concealed for over 18 months?
  7. Have agents Whitehouse, Sifuentes, and Torralva faced any internal discipline?
  8. Are these agents still serving at the Ajo Station, patrolling the community where they killed a resident?
  9. What was the TOPD officer's role in the shooting -- did the tribal officer fire as well?
  10. How has the community's refusal to call for help since the shooting affected public safety in Menagers Dam?

11. CURRENT STATUS (as of February 2026)

Criminal Case: PERMANENTLY CLOSED
- DOJ declined to charge (October 2023)

FINAL ASSESSMENT

Overall Confidence: HIGH

What We Know For Certain:
- Raymond Mattia, 58, U.S. citizen, Tohono O'odham Nation member, lifelong Menagers Dam resident
- Traditional singer, artist, sculptor, hunter, community council member, advocate against Border Patrol abuses
- Called law enforcement to report border-crossers on his property
- When agents arrived, cooperated: threw down sheathed knife, raised hands
- Agents issued multiple conflicting commands over 31 seconds
- Mattia pulled cellphone from pocket; agents fired
- Approximately 38 rounds fired; 9 struck Mattia
- Shot in back, abdomen, shoulder, buttock, forearm, elbow, both thighs
- Autopsy ruled death a HOMICIDE
- He was unarmed -- cellphone mistaken for weapon
- DOJ declined to charge (October 2023)
- Agents identified December 2024: Scott Whitehouse, Dan Sifuentes, Ivan Torralva
- $15 million wrongful death lawsuit partially stayed pending qualified immunity appeal
- Community no longer trusts or calls law enforcement

What This Case Demonstrates:

  1. Calling for help can get you killed -- Mattia did what communities are told to do: he reported a crime. The agents who came to "help" killed him at his doorstep. This has chilled the entire community's willingness to seek law enforcement assistance.

  2. Conflicting commands create impossible compliance -- Multiple agents shouting contradictory orders simultaneously made it physically impossible for Mattia to comply with all commands. His attempt to comply with one command was perceived as a threat and triggered the fusillade.

  3. A cellphone is not a weapon -- Agents fired 38 rounds at a man holding his phone. No one positively identified a weapon before firing. The "shots fired" context primed them to expect a gun; they saw what they expected to see.

  4. 38 rounds is not proportionate -- Three agents firing approximately 38 rounds at a man two feet from his front door who had just thrown down his only weapon and raised his hands. Nine bullets struck him. He was shot in the back.

  5. Toxicology as posthumous character assassination -- The government emphasized Mattia's intoxication in its defense. Being intoxicated at your own home on your own sovereign land does not forfeit your right to life.

  6. 18 months of concealed identities -- The government hid the agents' names for over a year and a half. They were only identified through civil discovery.

  7. Qualified immunity as architecture of impunity -- The agents seek to avoid not just trial but discovery -- the very process that would reveal what happened and why.

  8. Decades of militarized occupation -- This killing is the extreme expression of a 20-year occupation of sovereign indigenous land, where 809 complaints yielded 13 disciplinary actions, where teenagers have been run over, men shot, homes entered without warrants, and sacred sites bulldozed.

Raymond Mattia was a traditional singer. He sang all night during ceremonies. He called for help when strangers entered his home. Thirty-one seconds after agents arrived, he was dead. His cellphone lay on the ground next to his body.
