Salt Lake City police investigating whether officer fired firearm unintentionally at suspect

Newly-released body camera video shows what led to a Salt Lake City police officer shooting one of two suspects who earlier drove away from a Utah Highway Patrol trooper.

One of the investigations into the incident involves "the possibility that the discharge of the officer’s firearm was unintentional," according to the Salt Lake City Police Department.

On June 29, officers were called in to assist in locating the suspects, 51-year-old Bobby Joe Caster and 39-year-old Jack Colonna, after the trooper noticed the truck they were in was speeding with equipment violations. As the trooper turned around to perform a traffic stop, the truck drove away.

After the trooper found the abandoned truck, Salt Lake City police were called in to assist in finding the men in the area near 5650 West 700 South.

The body camera video footage shows officers tracking the suspects through heavy grass in a field. As a K9 handler finds Caster, another officer is seen drawing his firearm and instantly firing one round towards the suspect.

While officers order Caster to follow their commands, he can be heard saying he'd been shot in the hand.

Paramedics treated Caster on the scene for a gunshot wound to his hand before he was booked in the Salt Lake County Metro Jail on a federal hold. Colonna was later located and arrested without incident on outstanding warrants.
