Police have converged outside the Pennsylvanian home of a man thought to have been behind a killing spree in which six people were shot dead and another seriously injured in three locations.
The gunman was identified as 35-year-old Bradley William Stone and described by authorities as being armed and dangerous. Police also said he remained at large Monday, despite a flurry or action suggesting he may be holed up at a property in Pennsburg, about 30 miles northwest of Philadelphia.
Officers used a megaphone at the address to try to compel an end to their daylong pursuit of Stone.
"Bradley, this is the police department!” an officer yelled, according to The Associated Press. “Come to the front door with your hands up. You’re under arrest.”
Montgomery County District Attorney Risa Vetri Ferman said Stone was likely wearing fatigues and was known to use a cane or walker to assist him.
She said all the victims had a "familial relationship" to Stone.
The shootings occurred at homes in Harleysville, Lansdale and Souderton, three Philadelphia suburbs that are within a few miles of one another.
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 local newspaper The Lansdale Reporter that the couple had been fighting over custody of children.
Police responding to a second call about half an hour later found two people shot and killed in Lansdale. Two others were found dead in Souderton. Schools there were placed under lockdown, according to a statement on the school district's website.
"Due to police activity in Souderton and Harleysville, our schools have been placed in ‘shelter in place,’” the statement said. "All students are safe and are secured in their classrooms."
