The main suspect in a Philadelphia area shooting spree that left six dead is on the loose, the Associated Press reports.

The suspect, identified as Bradley William Stone, broke into the Harleysville, Pennsylvania apartment of his recently engaged ex-wife Nicole Stone Monday morning around 4 a.m., investigators said, before fatally shooting her and taking their two children with him.

Stone, a former Marine, proceeded to kill five others, all of whom had a “familial relationship” to him, Montgomery County District Attorney Risa Vetri Ferman said. The two children were reported to be safe.

Police originally surrounded a Souderton, Pennsylvania home, where two of Stone’s victims were found, for several hours believing Stone to be barricaded inside. Authorities are now reportedly searching Stone’s hometown of Pennsburg.

A man suspected of killing five people in a Philadelphia area shooting spree Monday is believed to have been traced to a house where police are currently responding.

The Associated Press and WPVI-TV Philadelphia are reporting that SWAT teams are surrounding a home in Souderton, Pennsylvania, where police say the suspect has barricaded himself. The house, according to police, is where two of the victims were shot dead.

Reports say that the first shooting was reported in the Lower Salford township in Montgomery County, Pennsylvania at 3:55 a.m. EST, where a woman was found shot dead. A second shooting, where two more were found killed, was called in at 4:25 a.m. EST. According to WPVI, all victims were shot at a close range.
