RIVERSIDE, Calif. -

A custodian accused of stealing guns from an evidence locker and snatching other items belonging to personnel at the Riverside Historic Courthouse was charged today with multiple counts of grand theft.

Matthew Anthony Warrick, 26, was arrested Tuesday after a Riverside County sheriff's investigation into thefts at the downtown Riverside courthouse, located at 4050 Main St., led to the recovery of alleged stolen goods at the defendant's home.

Warrick is charged with three counts of grand theft and four misdemeanor counts of petty theft.

The defendant, who's being held in lieu of $50,000 bail at the Smith Correctional Facility in Banning, was slated to make his initial court appearance this afternoon at the Riverside Hall of Justice.

According to sheriff's Sgt. Mike Manning, Warrick came under suspicion during a burglary investigation initiated last Tuesday after bailiffs discovered two firearms secured in an evidence locker at the Historic Courthouse were missing.

Detectives were also informed that the personal effects of several court employees had been stolen, Manning said.

Following up on leads, investigators obtained and served a search warrant at Warrick's residence in the 3500 block of 21st Street in San Bernardino.

``The warrant resulted in the recovery of both stolen firearms and a third firearm reported stolen from the city of Los Angeles,'' Manning said.

Other property allegedly taken by the defendant was also seized, according to the sergeant, who said Warrick was arrested without incident.

According to sheriff's officials, he is employed by Burbank-based Diamond Contract Services Inc., with which the county court contracts for janitorial work.
