His body was discovered at 1:38 p.m. Tuesday near W. 4th Street and Schoolhouse Road North Hanover Township, District Attorney Risa Vetri Ferman said. The location is about a half mile from the former Marine's home where SWAT teams have been methodically searching for the man for the past two days.
It appears Stone took his own life through "self-inflicted cutting wounds to the center of his body," Vetri Ferman said. A knife was discovered nearby, she said.
Police also found a video recorded by Stone on a cell phone on or near his person, law enforcement sources said.
Stone, 35, had not been seen since just before 5 a.m. Monday as he rushed his screaming children out of their mother's apartment in Harleysville. Moments before, neighbors and police said he gunned down the woman, Nicole Hill Stone. She was the last of seven family members he shot that morning, prosecutors said.
The children were left in his neighborhood in Pennsburg and he fled, officials said. The girls, along with Stone's current wife and infant are now in protective custody, Vetri Ferman said.
Hill Stone's mother, grandmother, sister, brother-in-law and niece were all killed in the shootings. Autopsies on the victims have begun, the DA said.
The lone survivor is her 17-year-old nephew, Anthony Flick. He remains in serious, but stable condition and is surrounded by family at Thomas Jefferson University Hospital in Philadelphia, the DA said.

A vigil will be held for the victims at 6 p.m. along Broad Street in Souderton.
Prosecutors released an updated photo of Stone, an apparent selfie, found on his personal cellphone when it was recovered along with his vehicle. Taken in November, Stone wore what appeared to be a green military jacket, red beard and a vacant expression on his face.
A digitally-enhanced version, sans-beard, was also released because prosecutors believe that it more closely depicts his current look.

Vetri Ferman said eight SWAT teams searched many locations known to Stone during their first day effort. However, none turned up clues about his whereabouts. Detectives did find some forensic evidence, but didn't elaborate as to what was found.
A supposed sighting of a man that fit Stone's description involved in an attempted carjacking in Doylestown Monday night "did not appear to be valid," she said.
Police, bolstered with help from Pennsylvania State Police, the FBI and U.S. Marshals, focused their efforts on Tuesday in the northwest part of the county where he lived and frequented, Vetri Ferman said.
The district attorney thanked the public for their assistance and patience. Schools in Upper Perkiomen, where Stone lives, were closed Tuesday and other districts - Souderton and Pennridge - were under lockdown.
Comment: This is such a sad and needless tragedy.
