A horrific murder-suicide on Long Island, New York, left five people dead and reportedly occurred before a family met with a real estate agent to sell a recently deceased woman's home.
Nassau County police arrived at the home on Wyoming Court in Syosset around noon Sunday, about 30 miles east of New York City.
Responding officers found the gunman outside the building, dead from a self-inflicted gunshot wound, authorities said. They found four other victims dead inside the home.
Police did not immediately identify the victims.

Mary Macaluso, a local real estate agent, told local newspaper Newsday that she was supposed to meet with a group of relatives at the address to discuss selling the home following the death of its owner and the family matriarch.
“All the kids were here for the funeral and they asked me to come see the house,” he told the paper. One of the brothers had reportedly asked for the meeting while other relatives were in town from Florida for the funeral.
Fox News Digital could not immediately reach Macaluso for comment on Sunday.
Records and an online obituary show that Theresa Martha DeLucia, 95, is the home's most recent resident and was buried last week, Newsday reported.

A couple who live in the neighborhood told FOX 5 New York that the suspected gunman was in his 60s and had recently lost his mother, who was in her 90s.
The couple said the son and mother had been living in the neighborhood for years.
“I didn't think that… he would take his whole family, his brothers. I thought maybe he was distraught and that he did it to himself,” the neighbor told the local station.
“This is really heartbreaking. This is such a quiet neighborhood, they used to call it a bedroom community. It's shocking,” another neighbor told FOX 5.
