Fire marshals are on the scene of a massive house explosion on Long Island, looking into what caused the blast that propelled a man to the front lawn of the home.
Firefighters in Syosset responded to the call at about 12:30 p.m. Thursday, and found the house on Alexander Drive totaled and the man severely injured. He is in critical condition, according to officials.
There was no fire or smoke when firefighters arrived, but "the house definitely exploded," according to Syosset Fire Chief Robert Kaplan.
"Roof has been blown up, the walls have been blown off their foundation and the floor has collapsed," said Kaplan. "The floor is now in the basement."
Kaplan said the Nassau County Bomb Squad and fire marshals are involved in the investigation. The explosion is being called suspicious until a further determination is made, said Kaplan.
No one else was inside the home at the time of the explosion.
