Kevin Bell, the first Hartford firefighter killed in the line of duty in four decades, had alcohol and a primary substance found in marijuana in his system when he died fighting a fast-spreading house fire, a state toxicology report reviewed by The Courant reveals. But the seven-member panel convened by the city to investigate the death and problems within the fire department never received the toxicology results, according to Hartford Fire Marshal Roger Martin, who was chairman of the board of inquiry.
