time of death at 9:25pm...

pretty sure that is when he was declared dead. By that point in was in the emergency room

the time line is something like the cops called for an ambulance at 8:22PM.

The ambulance workers found him unconscious when they got there and they put him in ambulance and he went into cardiac arrest. They tried to revive him a few times and eventually they was an official call of death.

this apparently is not unusual
