On a quiet Saturday afternoon in December 1975, the Diggs family home in Teaneck, New Jersey became the scene of a brutal multiple homicide. Wesley Diggs returned to find his 17-year-old daughter Audrey lifeless on a bed in her brother’s room; the mattress was soaked in blood. Investigators later found the bodies of Wesley’s wife, Jean, in the basement recreation room and three other children — Allison, 16; Wesley Jr., 12; and Roger, 5 — dead in their bedrooms. All five had been shot multiple times with a .22-caliber weapon.

There were no signs of forced entry, suggesting the killer or killers were known to the family and had been let inside. Wesley Diggs was treated as a person of interest but had a verified alibi and passed a polygraph; he was subsequently cleared as a suspect. Theories proposed at the time ranged from a robbery over business receipts to a suggestion by a Teaneck police lieutenant that Jean may have killed the children and then herself, but the evidence did not conclusively support that hypothesis, especially given that Jean sustained two gunshot wounds with one appearing to have been fired from a distance. No arrests were ever made.

The case grew cold and remains unsolved. Did anyone in the Teaneck area in December 1975 have information about visitors to the Diggs home or about disputes involving Wesley’s businesses?
