A former EMT murdered three of his siblings and a niece at their deceased mother's Long Island home. Authorities said the killer was upset about having to move out of the house after it was sold.

Joseph DeLucia, Jr., 59, was the lifelong resident of the Syosset home his 95-year-old mother, Theresa DeLucia, owned. Theresa passed away earlier last week, according to Nassau County Police Captain Stephen Fitzpatrick.
