Police near Philadelphia were hunting a man who killed six family members and wounded another in a Monday rampage that left dead bodies in three different homes, authorities said.

Montgomery County District Attorney Risa Vetri Ferman identified the suspect in the shootings in Philadelphia's northwest suburbs as 35-year-old Bradley William Stone. She said all of the victims had a "familial relationship" to Stone.

On Monday afternoon, police converged on a home in Pennsburg, about 30 miles northwest of Philadelphia, and used a megaphone to try 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."

WPVI-TV reported that a series of flash bangs could be heard at home in Pennsburg Monday afternoon.

Ferman said Stone was likely wearing military fatigues and was known to use a cane or walker to assist him.

The shootings occurred at homes in Harleysville, Lansdale and Souderton, three towns that are within a few miles of each other.

Neighbors at the first shooting scene in Harleysville said they awoke around 4 a.m. to the sounds of breaking glass and gunshots.

One neighbor, Evon Weron, said the suspect is a former member of the military and that the first victim was his ex-wife. Weron told the Lansdale Reporter the couple had been fighting over custody of children.

Police with armored vehicles and rifles flocked to Pennsburg after spending several hours at the Souderton home where several victims were found.

Several school districts ordered students and teachers to shelter in place.

Stone, a military veteran, is described as 5-foot-10, weighing 195 pounds, according to the Montgomery County District Attorney's Office. He has an auburn beard and mustache with closely cropped hair.

Anyone with information about Stone's whereabouts is asked to call 9-1-1 immediately.
