A man was arrested for killing three women–his mother, sister and an acquaintance–and seriously injuring a fourth in Hempstead early Saturday morning, Nassau County police said.
Bobby Vanderhall was charged with three counts of second-degree murder and one count of second-degree attempted murder.
Homicide Squad detectives alleged the 34-year-old suspect entered a Perry Street home and hit the victims with a hammer at 1:15 a.m. Saturday.
The victims were identified as 58-year-old Lynn Vanderhall, Melissa Vanderhall and Janel Simpson, both 29. Police did not identify the survivor, who was taken to a local hospital, where she is listed in stable condition.
The suspect will be arraigned Sunday at First District Court in Hempstead.
Homicide Squad detectives are continuing the investigation.
