Body in the Park / Ruby Street Shooting

In Philadelphia, Sergeant Irma Labrice and Detectives Leon Lubiejewski and Michael Gross don't have much time to find a murder suspect, and they don't have much to go on--the victim's body was burned beyond recognition. Meanwhile, on the other side of town, Detective Bill Kelhower and his team must gather enough physical evidence to crack a murder case because the witnesses to the crime aren't talking.
