Police: Philadelphia Man Ambushed Cop, Killed Civilian Police found a rambling letter after he was fatally shot By Newser Editors and Wire Services Posted Sep 17, 2016 7:22 AM CDT 54 comments Comments (Shutterstock) (Newser) – A wild chase and shootout through the streets of West Philadelphia left a civilian dead, two police officers and three civilians wounded, and a suspect fatally shot. Philadelphia Police Commissioner Richard Ross says Sgt. Sylvia Young was ambushed late Friday night and shot a number of times in the arm and protective vest, the AP reports. He says University of Pennsylvania police officer Ed Miller was also wounded. Both were in stable condition early Saturday at Penn Presbyterian Hospital. The suspect was cornered in an alley and fatally shot by police, the commissioner says. Police say the suspect left a "rambling" letter detailing his hatred of police and a parole officer, NBC Philadelphia reports. Young, a 19-year police veteran, was sitting in her vehicle at about 11:20pm when she was ambushed by the suspect, Ross says. Young was struck up to eight times, multiple times in her protective vest and left arm. The suspect fled, Ross says, and shot into a nearby bar, striking a security guard in the leg. The man then grabbed a woman and used her as a shield before shooting her in the leg. Moments later, as police gave chase, the suspect shot into a car, striking a man and a woman in the chest. The woman died early Saturday and the man is in critical condition in the hospital. Ross says Miller and two other police officers chased the man into an alley, where he was shot and killed.
