Three people are dead after an ambulance crash in west suburban Bellwood. The ambulance was transporting 48-year-old Larry Marshall Jr. home from dialysis treatment when police say the driver apparently lost control of the ambulance around 3:45 p.m. Saturday and slammed into a building at 28th Avenue and Washington Boulevard. Witnesses told police there were no other vehicles involved in the crash. Marshall was pronounced dead shortly after the crash. His mother, Minnie Marshall, said he had no children but was engaged to be married. The 51-year-old driver was killed instantly. Bellwood authorities said an ambulance attendant who was critically injured died Sunday.
