Police are searching for a suspect they say is responsible for the shooting deaths of six people and the serious wounding of another at three locations in suburban Philadelphia Monday.
CBS Philadelphia reports that law enforcement authorities in Montgomery County are searching for 35-year-old Bradley William Stone, of Pennsburg.Investigators say all of the victims have a "familial relationship" to Stone.
Police officers have converged on a home in Pennsburg, about 30 miles northwest of Philadelphia.
They are using a megaphone to compel an end to their daylong pursuit of Stone. "Bradley, this is the police department!" an officer yelled. "Come to the front door with your hands up. You're under arrest."
Ferman says Stone is known to use a cane or walker to assist him.
Stone is described as 5'10", 195 pounds, with a red or auburn beard and mustache with closely cropped hair. He is known to use a cane or walker to assist him. Stone may be wearing military fatigues, in either sand or green color.
Police are conducting an extensive search in and around Pennsburg, at both known and outdoor locations where Stone may be located. People in that area should remain in-doors, keep their doors locked and call 911 if they think they have seen the suspect.
Stone should be considered armed and dangerous. Anyone with information about Stone's whereabouts is asked to call 911 immediately.
