A Dakota County man has been sentenced to life in prison without parole for murdering his mother in Burnsville and later attempting to cover up the crime.

Court records show 58-year-old Troy Michael Mitteness was indicted by a grand jury in December 2024 on charges of first-degree premeditated murder and second-degree intentional murder.

The charges stem from the June 2, 2022 killing of his mother, 82-year-old Sandra Viola Mitteness, at their Burnsville home on Riverwood Drive.
