Hernandez led police on a foot chase as they attempted to take him into custody after observing him spray painting a vacant building.
Hernandez suffered an apparent seizure and died after an officer cornered him and fired his Taser at the teen.
Via Miami New Times:
The tape reveals that Hernandez was running from cops for a good seven minutes before he was caught. At one point (around 3:55), one officer wonders if the teenager escaped into the ocean.
Two minutes later (around 5:50), another cop says: "We're not gonna be bringing dogs out for this. We're gonna be looking to see if we find him. He's probably hiding out somewhere."
Roughly a minute later, cops suddenly announce they've caught Hernandez. There is no mention of Tasering the teen.
Thirty seconds later, however, a cop notices something is wrong. "Hey, you alright," one officer says.
"We don't know if the guy is having a seizure," a cop says before calling for an ambulance. "He is breathing."
Rescue workers arrive roughly four minutes later, after initially reporting to an address one block away.
Towards the end of the tape, cops refer to the situation as a "cardiac arrest."
