A Miami-Dade police officer who has been fired eight times from three different police departments may now be facing the end of his law enforcement career.

The Miami Herald is reporting that Opa-locka police Sgt. German Bosque attended an appeals hearing on Wednesday, where an arbitrator heard testimony to determine his fate as a police officer.

According to the Opa-locka police department, Bosque had left his police-issued AR-15 assault rifle with the father of his girlfriend, a violation of a 2008 settlement that allowed him to continue working as a police officer. The department is attempting to fire Bosque for the sixth time.

Bosque, who was fired in October, was defended at the hearing by the Miami-Dade Police Benevolent Association, which argued that Bosque had left the gun in a locked warehouse that only he and his girlfriend’s father had access to. Bosque is hoping that, once again, he will be reinstated with back pay.

According to the Herald report, Bosque has been accused over the years of beating a handcuffed suspect, beating juveniles, hiding drugs, stealing from suspects, defying orders, lying, falsifying police reports, and calling in sick to take a vacation. He is currently under investigation for the alleged battery of a domestic dispute suspect.
