An intensive manhunt is underway in Pennsylvania for a former Marine who has already shot 6 people and officials aren't sure if he's done yet.

35-year-old Bradley William Stone of Pennsburg, PA started his killing spree about 4:00 a.m. Eastern Time and the manhunt is picking up.

Of the 6 dead, all are related to him in some way, including what is believed to be his ex-wife with whom he was in a custody battle. She was also engaged to another man and conflicting stories say the children may have been present as he shot her. It seems as though he then took the children and then left them with a neighbor.

There is also a 7th victim who was wounded.

The former Marine served from 2002 to 2011. Details are still coming in.
