A quiet Syosset neighborhood was shaken after five people were found dead at a home on Wyoming Court, in a tragedy Nassau County police investigated as an apparent murder-suicide.
Police responded to the Long Island residence after reports of gunfire on August 25, 2024. Investigators found four people dead inside the home and another person outside. The deaths were determined to have resulted from gunshot wounds, rather than a stabbing.
Authorities identified Joseph DeLucia Jr., 59, as the person responsible for killing four family members before taking his own life. Investigators said the incident followed a dispute involving his late mother’s home and questions surrounding its inheritance and potential sale.
The victims included DeLucia’s siblings and niece, according to authorities. The case deeply affected the Syosset community, where neighbors were confronted with the sudden loss of several members of one family.
While the tragedy has sometimes appeared in online searches alongside references to a “Syosset stabbing,” available official and reputable reporting identifies the Wyoming Court deaths as a shooting and apparent murder-suicide.
The incident remains a painful reminder of how quickly family disputes can become devastating. For relatives, friends and members of the Syosset community, the loss represented not simply a news event, but the sudden disappearance of several lives and relationships.
Note: If you are referring to a new Syosset stabbing in August 2026, rather than the 2024 Wyoming Court case, that specific incident needs separate confirmation before it can responsibly be reported as current.
