SOUTH FORSYTH — A south Forsyth man whose daughter and two young grandsons were shot to death during a domestic violence incident in July, in which the shooter also killed himself, died over the weekend.

Jerry David Manning, 75, was taken to an area hospital from his home on Friday, according to Forsyth County Sheriff's Cpl. Robin Regan. He was later pronounced dead at the hospital.

Manning had been hospitalized since the summer, having been released to his Old Atlanta Road home — where the July shooting occurred — just “days before passing away,” Regan said.

A cause of death is being investigated due to “unreleased health issues in addition to recovering from multiple gunshot wounds.”

An autopsy will be conducted at the Georgia Bureau of Investigation’s crime lab.

Manning was one of four family members killed by a 32-year-old man in the early morning hours of July 22. The gunman was described as the longtime boyfriend of Manning’s 37-year-old daughter, Rebecca Jo “Beckie” Manning.

The couple had reportedly had a verbal fight the night before.

After the rampage, the shooter called his mother to tell her he had killed the family and was about to shoot himself.

She called 911, but he was dead when deputies arrived.

Rebecca Manning’s two sons, Jared Will Smith, 8, and Jacob Jerry Dean Smith, 9, were found dead in their beds. She was pronounced dead a short time later at the hospital.
