The Salt Lake Police Department's experimental program allowing officers to carry semiautomatics suffered what might be its first setback when an officer discharged his 9mm handgun in police headquarters.

A shooting review board will convene soon to investigate officer Elden W. Christen-sen, who was in the crime lab at the Public Safety Building, 315 E. Second South, Thursday evening when his Glock 9mm handgun fired. The round struck the floor and fragmented, a portion striking a ceiling vent, according to a police report.No one was injured.

The police department, which for a decade prohibited the semiautomatic, began allowing officers to carry the weapon in January under an experimental program. According to the new policy, the police chief may discontinue or alter the program at any time.
