Rochester, MN (KROC AM News) - A rural Rochester woman was arrested Monday after running over her adult son - intentionally.

Olmsted County Sheriff’s Office Capt. Scott Behrns says 58-year-old Cynthia Grund and her 37-year-old son got into a confrontation at her Salem Corners-area home because he had been drinking all day. Behrns says Grund told her son to leave and he left on foot, saying he was walking to Rochester

Grund then made arrangements for her son to stay somewhere for the night. Behrns says Grund got into her vehicle and caught up with her son as he was walking on the driveway. She told him to get into the vehicle and they got into another confrontation.

Behrns says the son then laid down on the driveway and told Grund, "Why don't you  just run me over?" - and she did. Behrns says the son suffered serious pelvic and other injuries. As of Tuesday afternoon, he was listed in critical condition at St. Marys Hospital.

Behrns says Grund told investigators, "He didn't believe I would run him over."

Grund was arrested on a felony assault charge.

Grund is a sister of Lois Riess, who is accused of murdering her husband in their Blooming Prairie home March 21 last year. Riess is currently being held in Florida where she has been charged with killing a woman while on the run.
