The male suspect is dead, he said. Employees of the Valley Transportation Authority were among the victims, and the extent of their injuries was not immediately clear, Davis said.Authorities received 911 calls at about 6:34 a.m. PT saying there were shots fired near a VTA control center, a hub that stores multiple light rail trains and a maintenance yard, Davis said. Multiple law enforcement agencies and Fire Department personnel responded to the incident using their “active shooter protocol,” Davis said.VTA Board Chairperson Glenn Hendricks said the shooting occurred in the rail yard but not in the operations control center.
