How exactly the former Marine suspected in this week's killing spree in Montgomery County, Pennsylvania, died is unclear after an examination by the county's coroner.
Coroner Dr. Walter Hoffman tells NBC10's Deanna Durante there was no sign of trauma to Bradley Stone's center region, contradicting information released by prosecutors on Tuesday.
District Attorney Risa Vetri Ferman had said at a briefing Tuesday that it appeared Stone took his own life and had "self-inflicted cutting wounds to the center of his body." She did add, however, they were awaiting an official report by the coroner.
Hoffman initially said Stone suffered no trauma to his body, then clarified that although the 35-year-old did have a cut to his leg, the trauma was not something that caused his death. He did not say whether it were self-inflicted.
Sources said there were two medicine bottles found on Stone's body and that one contained a crushed-up powder substance. An energy drink container with powder on the rim was also recovered, sources said.
Hoffman said he is awaiting toxicology results to make a final determination on how Stone died. He has expedited the testing and expects an answer by next week.
An intense manhunt was launched Monday for Stone, after prosecutors say he shot or stabbed his ex-wife Nicole Hill Stone and six members of her family early Monday. Six of them died. Hill Stone's 17-year-old nephew Anthony Flick is the lone survivor. He suffered a gaping head wound and serious cuts to his arm.
Stone was found dead in the woods near his Pennsburg home Tuesday after two days of searching.
The coroner has also released autopsy information, along with the official causes of deaths, for Stone's victims.
Stone's ex-wife Nicole, 33, was shot multiple times, just feet away from the couple's two daughters, aged 8 and 5. Nicole's mother, Joanne Gilbert, was shot in the head and had cuts to her neck. Grandmother Patricia Hill, 75, was shot in the head.
Nicole's sister, Trisha Flick, 36, was shot in the head and also suffered gunshot wounds to her arm. Her husband A.J. Flick had "chopping" injuries to his hands and head. Tricia and A.J.'s 14-year-old daughter, Nina, also died from chopping wounds to her head.
A large handled machete and a double-bladed axe-type instrument were found near the Stone's body, according to sources. They both appear to be coated in blood.
The Department of Veteran Affairs says Stone had post-traumatic stress disorder but that he didn't have any suicidal or homicidal thoughts when he met with his psychiatrist on Dec. 8.
