Prosecutors say they're still searching for a man following the shooting deaths of six people at three houses in the Philadelphia suburbs.
Montgomery County District Attorney Risa Vetri Ferman said Monday investigators don't know where Bradley William Stone is or how he's getting around.
Ferman says he's suspected of killing his recently engaged ex-wife and several members of her family, including her 14-year-old niece.
Ferman says investigators have recovered Stone's cellphone and his car. She says the 35-year-old Stone might not need a cane or walker he's been known to use.
