California has been plunged into mourning again as authorities investigate the latest of back-to-back mass shootings that have left 18 people dead.
California reels from two gun massacres
A deadly rampage by a 67-year-old suspect in northern California was likely an act of workplace violence, authorities say, offering fresh details about the second in back-to-back mass shootings that killed 18 people and horrified the nation.
In two separate shootings within three days, 11 people were killed at a Los Angeles-area dance hall and seven others were murdered at two farms in the seaside town of Half Moon Bay near San Francisco.
Authorities said they still were trying to determine motives for both shootings.
Preliminary evidence indicated the massacre in Half Moon Bay was a case of workplace violence and the gunman had used a legally-owned weapon. In the southern California shootings, officials have declined to make any statement regarding a possible motive.
