Three Suffolk fire departments responded to a Copiague house fire Monday in which a resident was found bleeding from a self-inflicted neck wound as the house went up in flames, officials said.

The 1 p.m. blaze on Halycon Road was extinguished in about a half-hour, said Copiague Fire Department Chief Mark Rosenberg, who added that one firefighter was treated for exhaustion.

Copiague firefighters received help from the Amityville and Lindenhurst departments, he said.

Rosenberg said the home was destroyed and the house next door was in danger of severe damage.

“We saved the house next door,” he said, adding the structure received some damage on its siding.
