AUSTIN (AP) -- The 23-year-old man suspected of killing retired attorney Richard Cotter and Cotter's friend before setting the house on fire had a fight with him nearly a year ago that led to his forcible removal from the house.
The suspect, who is related to Cotter, was arrested Saturday at a Minneapolis treatment center and later moved to the Mower County jail.
Prosecutors asked for an extension until Friday to file charges against the suspect. Sheriff Barry Simonson said investigators have not identified a motive, and the suspect has refused to answer questions.
Last March, the suspect and Cotter fought at Cotter's home, and Cotter called sheriff's deputies to remove him, Simonson said. He said the man was taken to a treatment center at that time.
Authorities believe the fire began one or two hours before it was reported by a neighbor about 5:15 a.m. Thursday. They believe Cotter was stabbed to death but are still trying to determine how Cotter's friend, Mary F. McIntyre, 68, of Baltimore, died. There were no stab wounds on her body.
