Cynthia Grund's 37-year-old son didn't take his mother seriously when he lay down on the dirt driveway and blocked her car on Monday afternoon. "Why don't you just run me over?" he told her. So she did.
Police say the victim was drunk when he lay flat on the dirt driveway and challenged his mom to run him over.
"He didn't believe I would," she reportedly told Olmstead County, Minnesota deputies. "He has been drinking all day. We gave him a chance," she added.
Officials say Grund was sober when she pressed the accelerator and ran her son over with her car.
She was arrested on second-degree assault charges, the NY Daily News reports.
Police say the victim is hospitalized with "significant" head and pelvic injuries.
Grund's husband, the victim's stepfather, called police after the accident.
The Grund's neighbor Samuel Haefner told The News the Grunds were always friendly, and "always willing to help out within our community. I would never describe them as off or malicious in any sort of way."
But apparently, violence runs in the Grund family.
Grund's sister, Lois Reiss, is set to stand trial in Minnesota for killing her husband David in March, according to KIMT3. Reiss, 44, is also awaiting trial for attempted murder of a woman in Florida.
