SAN DIEGO - A mechanic at a bus depot in downtown San Diego shot a co-worker to death and critically injured another early Tuesday before being killed by police, authorities said.
After finishing his shift around 2 a.m., Lonnie Glasco walked into a lounge area and shouted ''nobody's going to leave'' before heading out to a parking lot and firing several shots, police Capt. Jim Collins said.
Arriving officers found Benjamin Mwangi, 37, dead on the ground at the Metropolitan Transit System facility and Glasco, 47, holding a handgun at his side. He ignored repeated demands to drop the weapon and used his other hand to make a cellphone call, Lt. Kevin Rooney said.
''When the call ended, he started to raise the gun at the officers and they shot him,'' Rooney said.
Three officers fired their weapons.
Rooney said the officers were not close enough to hear what the man said during the phone call, and investigators were trying to find out who the gunman called.
After the gunman was shot, employees alerted officers to a second victim who was critically wounded in an office. The injured co-worker was on life support and not expected to survive, Rooney said. His name was not released.
Rooney said investigators have ''some indication'' of the motive for the shooting, but he declined to elaborate.
The shooter was identified as a mechanic on automated bus fare boxes who had worked for the transit system for about 30 years, agency spokesman Rob Schupp said.
The wounded man was a bus mechanic who worked for the transit system for 31 years. The slain employee had been a foreman for about four years, Schupp said.
At the time of the shooting, about 10 other employees were working at the facility near the Petco Park baseball stadium.
The transit system bus and rail services to the three million residents of San Diego County.
