A veteran has left six people, all believed to have familial links to the shooter, dead in three locations near Philadelphia in Pennsylvania.
A gunman, named as Bradley William Stone, 35, has killed six people and wounded one in three locations near Philadelphia, in Pennsylvania. All of the victims are believed to have had a familial link to the shooter.
The shootings in Souderton, Lansdale and Harleysville began at about 04:00 local time (09:00 GMT), according to local media reports.
The first shooting took place at the home in Souderton of Mr Stone’s former sister-in-law, Patricia Flick. She was killed along with her husband, Aaron Flick, and the couple’s daughter, Nina, 14. The couple’s 17-year-old son, Anthony Flick, was badly wounded.
The next shooting was at a house in nearby Lansdale where Nicole Stone’s mother, Joanne Hill, and grandmother Patricia Hill were killed.
Nicole Stone was later killed at her home in Harleysville. Neighbours reported seeing Mr Stone fleeing with their two children and raised the alarm.
Reports said that the shootings may have been triggered by a custody dispute. The children were reported to have been found safe a short distance away.
He is understood to be a military veteran who, according to local reports, had been diagnosed with post traumatic stress disorder. All the victims were reported to have been shot at close range.
Police have since surrounded a home in Pennsburg known to have been Stone’s residence, and it is currently believed that he is barricaded inside, with police warning the public that Mr Stone is “armed and dangerous” and to stay indoors.
