Authorities released the name of a man whose body was found inside a burning Omaha building. He was identified as 40-year-old John Lucas Jr., a homeless man. Fire Capt. Tim McCaw says a preliminary autopsy report shows Lucas died from inhaling smoke and other products of combustion. The fire started a little before 4:30 a.m. on Tuesday. Lucas' body was found on the second floor of the building, which was abandoned and once housed a tavern. The cause of the fire is still being investigated.
