We've got shots fired. Shots fired. Get under that truck. To the right. To the right. >> A federal arrest warrant, four law enforcement agencies, and one man barricaded inside a Yuma County house with a rifle. In the next few minutes, that house becomes the center of a gun battle involving over 100 rounds, and almost all of it is caught on one agent's body camera. Minutes earlier, it looks like a routine warrant service. Yuma County Sheriff's Office records the date as January 22nd, 2025, just after noon. Though the body camera file released months later carries a January 21st timestamp, a discrepancy that is [music] never publicly resolved. The location is not in question. The 10200 block of East 37th Street in the Fortuna Foothills area of Yuma County, Arizona. US Marshals Service deputies arrive with US Border [music] Patrol agents, Yuma police officers, and Yuma County Sheriff's deputies. The target, 48-year-old David Lee McKinney of Tucson. Three days earlier, on January 19th, McKinney allegedly shot and killed two men. 57-year-old David Dubois Johnson and 55-year-old Clinton Eric Dale during a gathering on West Laguna Street in Tucson. Detectives secured a warrant charging him with two counts of first-degree murder. Now, officers surround the house where he's staying. The Border Patrol agent wearing the camera has had [music] it deployed since the program expanded in 2021. It rides at chest height, and it does not see everything the agent sees. There's another detail that matters here. Once activated, the camera holds a 2-minute buffer of silent video recorded before the audio starts. Whatever this footage shows in its opening seconds may have already been unfolding unheard for up to 2 minutes [music] before anyone spoke a word into it. Deputies order everyone inside to come out with their hands up. >> Hands up! One at a time! The police, US Marshals. Slowly come out of the residence with your hands up. Keep the door open. Slowly come out with your hands up. All the way to the side. Oh. Guys up. Hands up. Slowly come out. Continue coming my way. Continue coming this way. You stop. Ma'am, take two steps to your left with your hands in the sky. Sir, with your right hand grab the back of your shirt. >> Two people inside comply. They walk out, hands raised, and are detained without incident. Then McKinney appears at the door. >> With your hands up! One at a time! The police, US Marshals. Slowly come out of the residence with your hands up. Keep the door open. Slowly come out with your hands up. All the way to the side. Oh. Guys up. Hands up. Slowly come out. >> For a moment, it looks like he's about to surrender. He isn't. McKinney turns and goes back inside. >> Your hands up! >> He's not showing his hands. >> Let me see your hands, sir. >> Ma'am, ma'am, ma'am, move over. Come over here. >> Officers reposition. Commands turn to warnings. And then, the moment the operation stops being a warrant service and becomes something else entirely. >> Get under that shirt. >> Hands up! >> I've got her in this garage door. >> According to the US Customs and [music] Border Protection account of the incident, McKinney has come back out armed with an AR-15 >> [music] >> and opened fire on officers positioned outside. The first of what CBP describes as several separate volleys over the next few minutes. The body camera [music] worn by one Border Patrol agent is running, but its view is limited, mounted at chest height, showing only a slice of what the agent can actually see. Officers scatter for cover behind vehicles and structures, trying to work out where the gunfire is coming from. >> Where's he shooting from? >> I don't know. What? Is that the garage door? >> I can't see it, no. >> No, I mean like the garage door, yeah. >> Yeah. >> Yeah, I'm going back up with him. Yeah, but I want to cover this in case he moves. >> Two officers watching the same structure, reading it differently. One focused on the front windows, the other refusing to leave the garage door uncovered. Neither is wrong. That's the problem. The house has [music] too many angles, and McKinney is somewhere inside all of them. >> He's got a gun. >> He's in the garage? >> He's in the garage door. >> Yeah. >> CBP's account states McKinney fires approximately 101 rounds toward officers during roughly 3 minutes barricaded inside the house. A Yuma County Sheriff's Deputy returns fire. Border Patrol agents set a perimeter and deploy less lethal munitions into the residence trying to force McKinney out without another exchange of gunfire. It doesn't work. When McKinney appears again, >> [music] >> this time in the garage, a US Marshal Service Deputy fires, followed by a Border Patrol agent. Then, silence from the house, but not stillness. Officers hold their perimeter [music] watching a structure they can no longer hear gunfire from. And now, according to CBP, they observe fire burning somewhere inside it. What started it is never established in the public record. Nobody is willing to walk into a house where an armed man may still be alive, still capable of firing, with flames spreading through the rooms between them. So, a Yuma police officer sends in a drone, a small aircraft doing what no officer can safely do yet, moving room to room through a burning, unsecured structure while a suspected active shooter is still unaccounted for. The operator guides it through the house until it finds him, McKinney, inside, not moving. Incapacitated, the drone operator determines. Only then do officers go in. They find McKinney unconscious with a gunshot wound to the head. Rural Metro Fire Department [music] personnel are called in and pronounce him dead at the scene. No law enforcement officers are injured. No one else in the neighborhood is hurt. The house on East 37th Street, where two unrelated occupants walked out with their hands raised less than 10 minutes earlier, is now a crime scene, an active fire, and the end of a warrant that started 3 days and 90 miles away in Tucson. The Yuma Regional Critical Incident Response Team, an independent unit created specifically to investigate officer-involved shootings, takes over the case. The deputies involved are placed on modified duty, standard [music] procedure while the investigation runs. The FBI, the Department of Homeland Security's Office of Inspector General, >> [music] >> and CBP's own Office of Professional Responsibility all respond to the scene, each with a separate mandate to examine what happened. Months later, CBP's National Use of Force Review Board completes its review and finds that the Border Patrol agents involved in the shooting acted in compliance with the agency's use of force policy, a finding that covers those agents specifically, not every officer who fired that day. David Lee McKinney is never tried for the killings of David De Bois The warrant that brought [music] federal, county, and municipal officers to a residential street in Yuma County closes not in a courtroom, but on the body camera of the agent who was there to serve it. 8 minutes and 50 seconds of footage released to the public more than 6 months after the fact, standing as the only complete [music] public record of how it ended.
