Man, 31, shot dead in North Philadelphia house

The hunt is on for a gunman who killed a man with a shotgun blast to the chest in North Philadelphia Monday night.

The victim was the eighth person shot to death in the last three days and the second murdered on Monday.

Police were called to a house on Lambert Street near Norris just before 5:30 p.m., Chief Inspector Scott Small said at the scene. When they arrived, they stumbled upon a scene of carnage inside the house: A 31-year-old man, whom police have not yet identified, was lying in a first-floor hallway, bleeding from at least one shotgun blast to the chest.

Medics pronounced the man dead in the house at 5:37 p.m.

Police said the motive of the shooting remains under investigation, but that there were signs of a struggle -- including several pieces of furniture knocked over -- inside the house. Police said that as far as they know, the victim and two potential suspects were in the house at the time of the shooting.

Small said two bare-chested men were seen running from the house just after the shooting, and several witnesses were taken to the Homicide Unit to speak with detectives. Cops brought a ballistics-sniffing dog to the scene in hopes of finding the shotgun the shooter may have discarded in the area, but came up dry as of 8:30 p.m.

"We believe the shotgun could be ditched somewhere nearby," Small said. "We've had good luck with [ballistics dogs] in the past."

Investigators said they found two shotgun slugs inside the house near the victim's body. They said they do not believe the man lived in the house where he was killed.
