A man with a shotgun opened fire inside a surburban home, critically wounding his estranged wife and killing his daughter and mother-in-law before turning the weapon on himself, police said.

Officers responding to calls of a shooting Friday afternoon found the man and his 65-year-old mother-in-law dead from shotgun wounds inside a small white house in Roslyn Heights, about 20 miles east of Manhattan, police said.

The man's estranged wife and their 17-year-old daughter were hospitalized, and the teenager later died. The wife is listed in critical condition but is expected to survive, police said.

Nassau County police Sgt. Richard Laursen said the couple were estranged and in the process of getting a divorce.

Neighbors said a violent argument erupted on the front lawn of the house early Friday over an upcoming move, Laursen said. A moving truck was parked in front of the house, where the woman and teenager lived, he said.

Neighbors later saw the man come back to the house carrying a sports bag.

A shotgun was recovered in the house.
