MADISON, Wis. (AP) -- Prosecutors have charged a former Wisconsin sheriff's deputy with killing his wife and sister-in-law last week.
Dane County District Attorney Ismael Ozanne filed two charges of first-degree intentional homicide against Andrew Steele on Friday. Steele would face mandatory life in prison if he's convicted.
Detectives believe Steele killed his wife, 39-year-old Ashlee Steele, and his sister-in-law, 38-year-old Kacee Tollefsbol, of Lake Elmo, Minnesota, in the Steele's home in Fitchburg on Aug. 22. Fitchburg, a city of 40,000, lies just outside Madison.
Steele resigned from the Dane County Sheriff's Department in June after he was diagnosed with amyotrophic lateral sclerosis, better known as ALS, or Lou Gehrig's disease. ALS attacks nerve cells and can lead to paralysis and death.
Steele was scheduled to make an initial court appearance Friday afternoon.
