Police have arrested the ex-boyfriend of a woman found stabbed to death Monday in her Island Park home.

Violet Karagiannis, 54, was found dead in her home on Lorraine Road. According to police, 43-year-old Ali Ceber, of Deer Park, broke into the home around 2 a.m. and stabbed Karagiannis at least 20 times because she wouldn?t get back together with him.

After the murder, police say Ceber turned himself in to officers on patrol in Deer Park. Ceber is expected to be arraigned on second-degree murder charges Tuesday.
