Joan, Jason and Gary Deal were found slaughtered Oct. 30, 1978, in their home on Mays Landing Road in Folsom.

State Police are seeking new information from the public that could help solve the murder of a South Jersey family that’s gone unsolved for 40 years.

Three members of the Deal family — a husband, wife and their 3-year-old son — were found dead Oct. 30, 1978, in their Folsom home by state troopers.

Local and federal law-enforcement agencies investigated the original crime, and numerous suspects were developed, but no one was charged, State Police said in a news release.

Both ballistic and DNA evidence collected from the original crime scene have been resubmitted for additional testing, thanks to new technological advances, the news release Wednesday said.

Gary Deal, 26, was found lying on the floor near the front door with his throat cut and was shot in the head multiple times. Gary Deal’s wife, Joan, also 26, was found naked on the bedroom floor, also shot in the head multiple times with her throat cut.

Their son Jason, 3, was found in bed with his throat slashed, the release said.

Investigators had determined the last time someone had contact with the family was the evening of Oct. 26, 1978.

The case has remained under investigation by the State Police Major Crime/Homicide South Unit since then, and State Police said Wednesday they’re seeking more information from the public.

State Police encourage people with information to call Detective Mario Nocito of the State Police Homicide South Unit at 609-561-1800, ext. 3354.
