At first it appeared to be another too common American story. A worker with a grievance goes on a deadly shooting spree, targeting his bosses and coworkers.
It quickly turned out that the killer was a former officer of the Los Angeles Police Department, who vowed to shoot as many of his former officers as he can, as well as their family members.
The LAPD says the killer is Christopher Dorner, who shot and killed a young woman who was the daughter of a former police captain, as well as her fiance. He then ambushed a police car, killing one officer and wounding another.
