MASSAPEQUA - Fire officials say a raging fire killed a husband and wife at a home in Massapequa this morning. The flames erupted at about 4 a.m. at the home on Nancy Place. Fire officials say the victims, Gary and Toni Munsch, were the sister and brother-in-law of the homeowner, Larry Cheramonte. The couple lived in an apartment attached to the home.Neighbors say a houseguest smelled smoke and Cheramonte ran outside and tried to break down the door to the apartment to save his sister and brother-in-law. The fire, however, was too intense. Cheramonte suffered third-degree burns to his arms during his rescue attempt. Officials say two firefighters also suffered minor injuries while trying to battle the fire. The Town of Oyster Bay says the apartment where the Munschs lived was illegal, and fire officials say it didn't have any smoke detectors. Two smoke detectors inside the main part of the home were not working.
