SULLIVAN, N.Y. (AP) — A central New York man and woman have been found dead in what police believe was a murder-suicide.

Police SWAT teams surrounded a home in the town of Sullivan on Monday afternoon after receiving a report of a possible domestic shooting. Police entered the home around 6 p.m. and found the couple dead. Their names have not been released.

Madison County Undersheriff Robert Lenhart says the man had called a family member earlier in the day. That family member apparently went to the home to "try and help," Lenhart said, but called police after hearing gunfire.

Police continue to investigate.
