Joseph DeLucia Jr., a 59-year-old man from Syosset, New York, fatally shot four family members, including his siblings and niece, before taking his own life, following a family meeting about the sale of his late mother's home. Distraught over the impending move and fearing homelessness, DeLucia opened fire with a shotgun in the home just days after his mother's funeral, killing his brother Frank DeLucia, two sisters Joanne Kearns and Tina Hammond, and niece Victoria Hammond. Witnesses reported that he screamed about the act before turning the gun on himself in the front yard. Police noted that concerns about DeLucia's mental state were raised by neighbors prior to the incident, which could have potentially triggered intervention under 'red flag' laws. Authorities emphasized the importance of community vigilance and communication with law enforcement regarding signs of distress. The incident has raised questions about mental health support systems and gun access in similar situations.
