6 dead, suspect on loose in suburban Philadelphia

          A man suspected of going to three houses in the Philadelphia suburbs and fatally shooting six people, including his terrified ex-wife and her 14-year-old niece, was at large Monday night, and a prosecutor said investigators didn't know where he was or how he was getting around.

Police recovered the cellphone and car of Bradley William Stone, who had recently been in court fighting with his ex-wife over custody of their two children. SWAT teams surrounded his Pennsburg home and pleaded through a bullhorn for him to surrender, but Montgomery County District Attorney Risa Vetri Ferman said it was unclear if he was there.

"As I stand here right now, we do not know where he is," Ferman told reporters at an evening news briefing.

The shooting rampage started before dawn at the home of Stone's former sister-in-law in Souderton and ended about 90 minutes later at ex-wife Nicole Stone's apartment in nearby Harleysville, Ferman said, correcting a timeline that had been based on when the crime scenes were discovered.

Nicole Stone's sister, Patricia Flick, her sister's husband, Aaron Flick, and the couple's 14-year-old daughter, Nina Flick, were killed in the first wave of violence, which wasn't discovered until just before 8 a.m., Ferman said.

Their 17-year-old son, Anthony Flick, was pulled from the home with a head wound around 12:30 p.m. and was taken in an armored vehicle and then by helicopter to a Philadelphia hospital for treatment.
