The man who shot himself to death inside a West Peabody woman’s home Sunday night after opening fire on her and her two daughters has been identified as Wilfredo Lorenzo, 47, of Aiken, S.C., Essex District Attorney Jonathan Blodgett’s office said today,

“Investigators have determined that Lorenzo and the victim at whom he was shooting were neighbors in South Carolina,” Blodgett’s spokeswoman Carrie Kimball-Monahan said. “The matter remains under investigation.”

The woman’s father, Tony Salvaggio, 68, told the Herald yesterday his daughter knew her assailant from when she was staying with family in South Carolina up until moving back home three weeks ago.

Salvaggio said Lorenzo walked up to his daughter’s car, pointing a gun, and shot at her and his grandchildren, ages 12 and 18, as they fled for their lives.

He said Lorenzo then walked into their house on Monson Drive and killed himself in the family room.

Peabody police confirmed Lorenzo fired several shots at the woman “with some of the rounds striking her vehicle.”

Surrounding homes were briefly evacuated while a SWAT team and crisis negotiator tried to coax Lorenzo out.

Lorenzo’s family could not be reached for comment.
