Investigators with the State Fire Marshal’s office have released the preliminary results of their investigation into a fire at the Colonial Manor Nursing Home in Anita. Jim Saunders, the Public Information Officer with the Iowa Department of Public Safety, says based on their preliminary findings, investigators have concluded that the fire was intentionally set, though local and state fire marshals are still investigating. The fire broke out shortly after 10:30 Saturday night, and was contained to a single room in one wing of the nursing home. Anita and Wiota firefighters responded quickly, but Saunders said the facility’s sprinkler system also gave them a head-start on containment of the flames. The sprinkler system helped prevent the fire from being more of a serious incident than it was. Firefighters say they hauled out a couple smoldering pieces of vinyl-covered furniture that created thick toxic smoke when the fire spread to them. Two people were treated at a local hospital for smoke inhalation — the resident in the room where the fire occurred, and the charge nurse who was on-duty that night. Saunders says the Cass County Sheriff’s office wants to hear from anyone who has information about the fire.
