While in one of the deputies' patrol vehicles, Rivera moved his handcuffs to the front of his body. He was moved to another patrol vehicle and started to resist. Deputies attempted to move his handcuffs to the rear of his body and in the process, Rivera became aggressive again and kicked a deputy in the chest, says the arrest affidavit.


While en route to TCSO Central Booking, Rivera reportedly told a deputy that once he got out of jail, he was going to kill them. According to the affidavit, Rivera said "don't you see what I was carrying, don't you think I have more guns." Rivera also told the deputy he was going to put a hit out on their son while Rivera was in jail.

Rivera also said, "I have been busting [shooting guns] all this time and y'all just now caught me." He also said he would kill the other arresting officers once he was released, says the arrest paperwork.

Bond has been set at $85,000 for all five charges.
