Police in Philadelphia and Camden searched Sunday for the killers in two separate shootings overnight that left a teenager and a man in his 40s dead. Later Sunday, another man was shot and killed in Philadelphia.

Officers responding to a report of gunshots in Southwest Philadelphia shortly before 4 a.m. Sunday heard about eight shots on the 8500 block of Bartram Avenue, police said.
