BEDFORD-STUVESANT - A man whose charred body was found bound with duct tape in a Bedford-Stuyvesant house died of asphyxiation, according to a medical examiner.

Firefighters found 21-year-old Earl Obermuller?s body in a ground-floor apartment at 186 Madison St. when they responded to the fire Monday night. Investigators say an accelerant was used to set the flames. Authorities have identified Obermuller?s address as E. 96th Street and police say they do not know why the victim was in the abandoned building.

Neighbors say the house, which has been empty for nearly a year, is frequented by squatters and drug users. Police do not have any suspects in the case.
