Police: Child advocate was ambushed, executed at bus stop

Surveillance images show that a child advocate was killed at a Philadelphia bus stop by someone who waited an hour for her to arrive.

Police need help identifying the man who shot 56-year-old Kim Jones in the back of the head.

Detectives say Jones was ambushed on her way to work Tuesday morning at a bus stop near Temple University. They say the killer left behind her purse, jewelry and cell phone.

Homicide Captain James Clark says Jones was clearly targeted. Police are seeking help identifying the male suspect seen on security images boarding a city bus.

Jones worked at a program that helped families with young children.

She leaves behind two children of her own.
