LIMESTONE - A man and woman were found dead and another man was sent to Hamot Medical Center, in Erie, Pa., shortly after noon, Wednesday.
Cattaraugus County Sheriff Timothy Whitcomb said an unidentified man and woman were shot to death by the ex-husband of the woman when she and her boyfriend approached the residence at 5340-5342 Nichols Run Road, in Limestone.
"What we have is a double murder and an attempted suicide," Whitcomb said. "We have a couple that was married no longer. The wife and her new boyfriend were going to the residence to retrieve some of her belongings. Her ex-husband was lying in wait for them."
After shooting the woman and her boyfriend to death, the unidentified man turned the handgun on himself, resulting in critical wounds, Whitcomb said.
"There was a witness to the beginning of the shooting," Whitcomb confirmed. "He very quickly put distance between himself and the situation to call our department."
The Cattaraugus County Sheriff's Office is "aggressively" making attempts to notify family of the victims, as well as the man that is alleged to have done the shooting, the sheriff said.
Whitcomb would not comment on the weapon, other than to say it was a handgun. He also would not comment as to how long the man and woman had been divorced.
The investigation is ongoing.
