A Stoughton man says he was high on meth and mentally unstable when he broke into a 78-year-old woman’s home and attacked her last January. A Dane County judge sentenced Joshua Radewan to two years in prison Wednesday based on his guilty plea entered last April. The woman said she was in her bedroom when he forced his way into her mobile home, started hitting her, then tore up the home’s interior. She ran to safety at her daughter’s home. Radewan was still inside when police arrived.
