From [HERE] The mother of a man shot and killed by Anaheim police filed a civil-rights and wrongful-death lawsuit Tuesday against the Police Department and city alleging that her unarmed son was fired upon from behind and then,  when he fell to his knees, shot execution-style in the back of the head.

The FBI also announced Tuesday it would review Saturday's shooting after Anaheim Mayor Tom Tait called for both a state and federal investigation, in addition to the probe by the Orange County district attorney. Manuel Diaz's mother and family filed the lawsuit in federal court, seeking $50 million.

They asked residents in Anaheim's heavily Latino core to refrain from violence. "This is wrong and needs to stop on both sides," his mother, Genevieve Huizar, said in a statement. Anger from the shooting boiled over Saturday as the wounded man lay handcuffed on an apartment complex lawn as bystanders shouted at police to get Diaz medical aid.
