A Stewartville man was given a stay of imposition after pleading guilty to assaulting a woman with a hammer, breaking the woman’s jaw.

Kenneth Alan Hartmark, 45, was sentenced in Olmsted County District Court Monday afternoon by Judge Kathy Wallace to five years of supervised probation on a felony third-degree assault charge, according to court records.

Hartmark received a stay of imposition for his conviction, which means if he completes all the conditions during probation, his sentence could be reduced from a felony to a misdemeanor. He was also ordered to serve four days in jail but was given credit for four days already served.

A felony charge of fifth-degree controlled substance possession was continued for the duration of his probationary period, which if he successfully completes the charge will be dismissed. A third felony charge, second-degree assault, was dismissed as part of the plea.

Hartmark, 45, was arrested the morning of Jan. 30 at his residence in the 2100 block of Eagle Drive Northwest in Stewartville. Olmsted County Sheriff’s deputies were called to the home that day and found a woman with severe facial injuries, unable to speak. Through written communication and later interviews, deputies learned that the woman had been hit from behind and did not see who hit her, Capt. Scott Behrns said shortly after the incident.

The woman told deputies she and Hartmark had begun using methamphetamine again recently and although Hartmark had never hurt her, he does “freak out” when on meth, according to court documents.

In the home, deputies found a medium-sized claw hammer. Inside Hartmark’s coat, deputies found a glass vial with 0.26 grams of meth in it, according to court documents.
