Police launched an intense manhunt in a Philadelphia suburb Monday after six people were found dead and one person seriously wounded at three locations, authorities said.

Bradley William Stone, 35, of Pennsburg, Pennsylvania, has a “familial relationship” with all the victims, the Montgomery County District Attorney’s Office said.

The district attorney’s office said Stone has used a cane or walker in the past and may be wearing military fatigues, in either sand or green color.

He was described as armed and dangerous.

Late Monday afternoon and early Monday night, the police search focused on Pennsburg, according to CNN affiliate WPVI.

WPVI reported the killing started about 4 a.m. when a woman was shot to death in an apartment in Lower Salford Township.

About half an hour later police were called to Lansdale, where two people were killed, and then to a home in Souderton, where the other victims were found, WPVI reported.

WPVI said police originally thought Stone was holed up inside the house, so officers surrounded the residence.

Heavily armed SWAT teams tossed flash-bang devices into the house and stormed the residence, police said Stone was not inside.

Stone served as a reservist the U.S. Marines until 2011, mainly as a meteorologist, according to the Marines. He served a few months in Iraq in 2008.
