In Syosset, Long Island, 59-year-old Joseph DeLucia Jr., distressed over the impending sale of his late mother’s home, fatally shot his three siblings and a niece before taking his own life. DeLucia, who had lived his entire life in the home, perceived he was being cut out of the will and feared displacement, though family members assured him he would be provided for. The tragic event took place three days after the funeral of his mother, Theresa DeLucia. Neighbors and officials noted DeLucia's recent emotional instability and past mental health issues, suggesting the incident might have been preventable through earlier intervention. The family had gathered to discuss the home sale with a realtor just before the shooting occurred. The incident underscores the importance of reporting mental health concerns, particularly when firearms are accessible.
