Three residents at a group home for the mentally disabled are dead after a fire swept through the facility late Wednesday night. Asst. Fire Chief Robert Mikel said the Amistad Residential Facility, in the 300 block of Norwood, had 13 men inside when the fire started around 10:40 p.m. Four men had to be rescued from the inside of the four-bedroom home. Mikel said one of the four died at the scene, two more died at the hospital and a 23-year-old man still remains at San Antonio Military Medical Center in critical condition. Chief Charles Hood said at a news conference on Thursday that the victims were 38, 42 and 65 years old. William Stull, Christopher Breeze and Eddy Lee died of carbon monoxide toxicity.
