The Emmet County woman accused of abusing her adoptive children pleaded no contest to the charges.
Kimberly Loesch pleaded no contest to third-degree child abuse Tuesday.
A no contest plea is not an admission of guilt, but is treated as such for sentencing purposes.
The investigation into Loesch and her husband Phil started in July of 2013 when their 13-year-old son went missing for two days.
"During the course of my search, my office received several tips as to why this young man may have left his home," said Sheriff Pete Wallin.
The boy was found two days later, but an investigation into accusations of abuse started.
The Loesch's turned themselves in to authorities.
Court documents alleged the children were deprived of food and restrooms and kept locked in an upstairs bedroom. Court documents also allege the children were beaten on their hands, heads and buttocks. They were also allegedly required to hold large buckets of water or rocks as punishment.
The documents also alleged the boys were mentally abused, being called "thieves" or "liars," and were told they were not loved, unwanted and should "run away for good."
