Woman sergeant shot in patrol car; female bystander killed; another officer and two others injured by gunman who left hate letter at the scene.

A gunman was shot dead in Philadelphia after he ambushed and shot two police officers and four civilians, killing one of the bystanders, in a 'targeted attack on police'.Philadelphia Police Commissioner Richard Ross said Sgt. Sylvia Young, 46, was ambushed late Friday night and shot a number of times in the arm and upper body but she was wearing a protective vest so survived. He said Ed Miller, a former police officer who is now a member of the police force at the University of Pennsylvania, was also wounded.

A note believed to be written by the shooter was recovered near Young's car. It allegedly contained rambling anti-police rhetoric and named a parole officer as a target, Ross said.
