A 33-year-old man was arrested for stabbing his elderly mother to death and seriously injured his older sister during a fight at their Babylon home on Friday morning, Suffolk County police said.
Kathleen Kearns, 59, called 911 to report that she and her mother, Mina, had been stabbed at the house they shared on Livingston Avenue at 7:20 a.m., police said.
Both victims were taken to Good Samaritan Hospital Medical Center in West Islip, where Mina was pronounced dead and Kathleen was treated for serious injuries.
Officers apprehended Joseph Kearns shortly later. Homicide Squad detectives charged him with second-degree murder and attempted murder.
He will be arraigned Saturday at First District Court in Central Islip.
