Elm Street Nightmare: Family Gunned Down

A man with shotgun walked into a house on Elm Street in the New York City suburb of Roslyn Heights, N.Y., and shot three women, including his estranged wife, before turning the gun on himself, police said.

Officers responding to reports of gunshots on New York's Long Island found Mohamed Shojaeifard, 49, and his mother-in-law, Batool Biraman, 66, dead of shotgun wounds, police said. His 17-year-old daughter Mandana was critically injured and died later that day in the hospital. His wife, Haleh Mohseni, 40, is expected to survive her wounds.

Nassau County Police Sgt. Richard Laursen said the couple was in the process of getting a divorce and that the wife and daughter were renting the home.

Neighbors said a violent argument erupted on the front lawn of the house early Friday over an upcoming move, Laursen told the Associated Press. A moving truck was parked in front of the house, he said.

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

"I heard three shots," neighbor Ambreen Saleen told Newsday. "I tried to go home and get my cell phone and dial 911. I'm shaking. It's terrible."
