A Moberly man has been charged in Callaway County after he allegedly tried to carjack someone while posing as a police officer on Tuesday.

Brian Koch, 28, was charged on Wednesday with carjacking, illegal gun possession, three counts of armed criminal action, two counts of illegal use of a weapon, a count of misdemeanor impersonating a law enforcement officer and two counts of tampering with evidence.

He is being held at the Callaway County Jail without bond. A hearing is scheduled for 8:30 a.m. Friday.

The probable cause statement says police were called to the Jefferson City Airport for an attempted carjacking. Koch was allegedly found by police with a knife, a fake plastic badge and a needle with methamphetamine, the statement says. Police eventually found a machete at the airport.

After he was detained, Koch allegedly told officers that larvae were eating his brain, court documents say. He was brought to St. Mary’s Hospital for evaluation before being brought to the jail.

The victim told law enforcement that she was sitting in her vehicle when Koch walked up to her vehicle, told her he was a police officer and asked for a ride, court documents say. The victim allegedly told him that she needed proof that he was an officer and Koch pulled out a gun and a machete, the statement says. He allegedly tried to get into the woman’s vehicle, but she was able to drive away.

A witness saw the interaction while sitting in her own vehicle, the statement says. She allegedly told police that she saw Koch drive in on a vehicle with a missing front tire before pulling out what appeared to be a badge and a gun, the statement says. The witness then drove away the same time as the victim.
