The bodies of Gary Deal, Joan Deal and their 3-year-old son Jason were discovered Monday, Oct. 30, 1978 inside a home on Mays Landing Road in Folsom, according to New Jersey State Police, who posted about the case on Facebook Wednesday.
“Ballistic and DNA evidence that were originally collected from the crime scene have recently been resubmitted for additional testing due to new technological advances,” State Police said.
Gary Deal suffered multiple gunshot wounds to his head, and his throat was slashed, police said. His body was discovered on the floor near the front door.
His wife, Joan Deal, was also shot multiple times in the head and had a slashed throat, police said. Her naked body was left on a bedroom floor.
Both parents were 26, according to police.
The throat of 3-year-old Jason was also slashed, police said. He was wearing pajamas and lying in his bed when his body was discovered.
