LAWRENCE, N.Y. (WPIX) -- A fire blazing out of control early Thursday morning at a laundromat in North Lawrence has left four people dead, including two children.

Nassau County police say a 46-year-old mother, her two daughters ages 9 and 10 and a 19-year-old male were killed as the fire spread into apartments above the laundromat.

Police spokesman Det. Lt. Kevin Smith said seven others, including four children, managed to escape the intense heat and flames by jumping out of second floor windows.

Seven fire departments responded to the call which came in at 5:38 a.m. The laundromat and the connected apartments, located on Lawrence Ave near Mill Street, were fully involved when firemen arrived on the scene. It took some three hours to finally extinguish the blaze.

The scene of the fire is not far from the Lawrence Long Island Railroad Station, St. Mary's cemetery and an elementary school. Officials believe this is the first fatal fire in which a child has died in Nassau County in four years. Those who survived the fire will be provided shelter, money for food and medicine by the Red Cross.

While arson investigators are on the scene,  the cause of the blaze has yet to be determined.

Family and friends of the victims have set up a fund to help pay for funeral expenses. Those who want to donate can send checks to: America Chavez, P.O. Box 550, Lynbrook, NY 11563
