The mother of an 8-year-old boy who was found hanging in a Pennsylvania basement last month alongside his 4-year-old sister told a 911 dispatcher he had been bullied and "had made threats of doing this but didn't want to go alone."

The dispatcher further quoted the mother as saying that the boy, Conner Snyder, “may be the aggressor,” Fox 10 Philadelphia reported Thursday.

Lisa Snyder, 36, called 911 after reporting finding Conner and her daughter Brinley hanging from the basement rafters of their home in Albany Township with a dog leash on Sept. 23.
