Killed were Sandy and Stephenie Mazzella, along with Sandy's mother, Elaine.
WAKE FOREST, N.C. — Several people called 911 last Friday to report the gunshots that claimed the lives of three members of the Mazzella family from New Jersey, according to published reports.
At least two of the callers were in or near the home when the killings occurred.
"My parents have been shot. He just came in with a shotgun and shot everybody," said a female caller believed to be the 14-year-old daughter of Sandy and Stephenie Mazzella.
The Wake County Sheriff's Office altered the 911 audio in an effort to keep the callers' identities anonymous.
Sandy and Stephenie were killed along with Sandy's mother, Elaine. All of the victims were from New Jersey.
"I just heard seven gunshots and people screaming right behind my house," says another caller. Another neighbor says, "There is a man with a shotgun standing right behind our house."
Judge dismissed restraining order before killings
Stephenie's adult brother, Joey, was outside walking the dogs when the killings occurred, according to family members.
Jonathan Frederick Sander, the next-door neighbor, entered the home and shot the family members to death, alleges Wake County Sheriff Donnie Harrison.
"My sister and brother-in-law are laying on the floor," says the caller.
"Is anybody awake or breathing?" the dispatcher asked.
"No," the caller said. "They got shotgunned. They're done."
Sander is being held without bond, charged with three counts of first-degree murder. He faces life in prison without parole or the death penalty if convicted.
A motive has not been released, although the sheriff says the families were feuding.
