A drunk driver ran a red light and slammed into a car, killing an off-duty police officer. When he started to flee the crash on foot, a good samaritan stepped into action, and it was caught on video.

A gut-wrenching video shows the moments after a horrific car crash took the life of an off-duty police officer in Lake Worth, Texas. A bystander captured not only the wreckage but also the efforts of a witness to bring the man responsible to justice.

Imagine this: It’s another ordinary night at Fuzzy’s Taco Shop when 26-year-old Dylan Molina decides to throw back at least eight double vodka Red Bull cocktails. Now, that’s not just asking for a headache the next morning, it’s a cry for disaster. His blood-alcohol level? Off the charts—more than twice the legal limit. Not exactly what you’d call a responsible night out.

“Eight doubles, 16 single shots, is more than anybody should have in a three-hour period. Maybe even at all,” said Lake Worth Police Chief J.T. Manoushagian. “Clearly, not in a good place to be operating a vehicle. Clearly intoxicated. He’s holding another one of those double vodka and Red Bull drinks there, and then he simply walks away.”

The night turned deadly fast. Minutes after leaving the bar, Molina, already involved in a minor crash, ran a red light and crashed into a sedan, killing off-duty Euless Police Detective Alex Cervantes. Cervantes’ family—his wife and two young children—survived with injuries. But can you even begin to imagine the horror they went through?

Enter Justin Gonzalez, the hero of our story. As Molina stumbles out of his vehicle, completely unscathed, Gonzalez doesn’t just stand there. He orders Molina to wait for the police. At first, Molina complies, but then—surprise, surprise—takes off running. Big mistake. Gonzalez chases after him, tackling Molina into a hedge of bricks. Talk about a hero!
