Here we go. >> Hey everyone, today we're taking a look at a case that shocked California and law enforcement agencies across America. >> Hello, man. >> How you doing? >> Where are the tags for your car? >> Uh they're in the I'll get them at the house. >> Huh? >> They're probably at the house. >> Probably? Is this your car? >> Yes, sir. >> Yeah? Can I see your driver's license and registration? >> Is that my license? This is my >> I'm sorry? >> My license is in my bag. >> Okay. >> Can I grab it? >> Yeah. >> Deputy Sheriff Isaiah Cordero, a 32-year-old officer who lost his life during what should have been a routine traffic stop. On that day, he was simply doing his job. Let me show you how an ordinary traffic stop turned into a nightmare. >> Who's the RP advising of the gun caliber? >> It's December 29th, 2022 in Jurupa Valley, California. Deputy Isaiah Cordero spots a suspicious black pickup truck and initiates a traffic stop. Nothing seems out of the ordinary. Cordero gets off his motorcycle and begins approaching the vehicle. Then, everything changes in an instant. Without warning, the driver pulls out a firearm and opens fire at point-blank range. The deputy collapses to the ground and the gunman speeds away from the scene. >> Isaiah. Hey, hey, hey. Isaiah. Can you hear us, brother? Can you hear me? >> This is the kind of ambush every police officer fears. >> Hey, listen to me. Can you hear me? No. Can we get this off? I got nowhere. I don't have anything. No idea what happened. I don't know if he's I can't tell if he's breathing or not. >> Get them back. Have them scoop back. >> I can't tell if he's breathing. I got a lock on him now. >> Get my AED. Nago. AED. >> AED now. >> Don't push him on his foot. >> Got it. Give me somebody to hold his head. Yes. Yes, it looks to the face. >> Officer Deputy Isaiah Cordero's body camera footage suddenly went dark after the deadly attack. The 32-year-old deputy was later pronounced dead, triggering a massive manhunt across Southern California. Investigators quickly reviewed the available body camera footage and combined it with footage from nearby Flock security cameras. Using this evidence, they were able to identify the suspect as 44-year-old William Shay McKay. McKay had an extensive criminal record and was reportedly associated with an outlaw motorcycle gang operating in Southern California. Law enforcement officials also noted his long history of violent offenses. Authorities immediately distributed a description of both McKay and his vehicle to law enforcement agencies throughout the region. Less than 2 hours later, an off-duty police officer spotted the suspect traveling southbound on Interstate 15. >> Bearcat coming up behind you guys. >> Keep an eye out for spikes. >> I don't see any. >> He said Golden West. Well, that's past the traffic. >> I showed you approaching heavy traffic. Approaching heavy traffic.

He's coming up though. >> What did he say? >> He's coming up to the spikes. >> Okay, the vehicle just went over the spikes. Spikes are clear. Vehicle is still number one >> The massive manhunt, 1:30 to 2:30. What happened next triggered one of the most intense manhunts in recent California history. Insert pursuit footage. Dozens of law enforcement vehicles chased the suspect along Interstate 15. Local news helicopters captured dramatic footage of the black pickup racing down the highway even after its tires were damaged by spike strips. The final confrontation looked like something straight out of an action movie. The suspect became surrounded by armored police vehicles. Instead of surrendering, he opened fire once again. Officers returned fire and the suspect was killed during the shootout. >> Speed on Interstate 15 mph. You guys are approaching heavy traffic to a full stop. >> Do you see a Bearcat? >> see a Bearcat. >> Oh, here it comes. I think he's going to come up on the right.

A BearCat tried to pull off a PIT maneuver, but Mckay was able to continue until the truck he was driving wound up on the shoulder, pinned in by deputies who say he opened fire on them, so they returned fire. A lot of it. >> Here we go. >> [screaming] >> He's under the bridge. >> [screaming] >> Suspect is down. Cease fire. >> Hey, HOLD YOUR FIRE. HOLD YOUR FIRE. CEASE FIRE. BACK IT UP. BACK it up. Back.

Back up. Back up. Back up. Back up. I got good Back up. He's definitely injured. And no movement. Stop him from breathing. >> William McKay >> The pursuit finally came to an end when William Shay MacKay was shot and killed by law enforcement officers. According to the autopsy report, MacKay suffered a total of 12 gunshot wounds. Six of the rounds struck his head, another penetrated his lungs, and a fatal shot to the neck severed his spinal cord. In total, officers fired 79 rounds during the confrontation. After securing the scene, investigators searched MacKay's vehicle. Inside, they discovered a bag containing a white powdery substance, the firearm used to kill Deputy Isaiah Cordero, several fraudulently obtained credit cards, and a membership card linked to a violent white supremacist outlaw motorcycle gang. MacKay's criminal history stretched back more than two decades. In 1999, he pleaded guilty to assault with a firearm and served three years in prison. In 2005, he participated in a violent home invasion robbery. During the crime, a man was choked and a woman was smothered while the suspect stole approximately $3,700. MacKay later pleaded guilty to first-degree robbery and two counts of assault, receiving a 13-year prison sentence. His criminal behavior continued after his release. In 2021, MacKay and an accomplice allegedly held a woman against her will after accusing her of participating in a burglary at his home. Rather than contacting police, MacKay reportedly assaulted the woman, bound both her and her mother with duct tape, and threatened to kill them. The victim eventually escaped and contacted authorities. Two days later, San Bernardino County deputies located MacKay driving a stolen truck. He and an accomplice fled into the desert where they were eventually surrounded by law enforcement. During the standoff, MacKay's accomplice stabbed a police K9. Following his arrest, MacKay chose to represent himself in court. A jury later found him guilty of false imprisonment, evading a peace officer, making criminal threats likely to result in death, and receiving stolen property. Although prosecutors pursued additional charges, court records show that a judge ruled MacKay not guilty of kidnapping because the victim had not been forcibly moved from the location where she was being held. While awaiting sentencing, MacKay's bail was reduced from $950,000 to $500,000 because California law allowed him to post only a portion of that amount through property collateral. He was able to secure his release. Before sentencing could take place, McKay was arrested on a separate drug-related charge and again posted bail. When he later failed to appear in court for sentencing, a warrant was issued for his arrest. That warrant remained active on December 29th, 2022 when Deputy Isaiah Cordero pulled McKay over for driving a truck without a rear license plate. Investigators later interviewed one of McKay's associates who stated that McKay had repeatedly said he did not want to return to prison. Just 1 week after the tragic shooting, Deputy Isaiah Cordero was laid to rest. Thousands of law enforcement officers, family members, and community supporters gathered to honor his life, service, and sacrifice. Isaiah Cordero was described by family, friends, and fellow officers as a kind and dedicated public servant who cared deeply about his community. His death left behind a grieving family, heartbroken colleagues, and a community searching for answers.
