ST. CHARLES (CBS) — A former St. Charles woman who did nothing to stop her boyfriend from beating her daughter was sentenced on Wednesday to eight years in prison.

Cathleen A. Koch, 30, had pleaded guilty to one count of aggravated domestic battery, obstructing justice and child endangerment.

On Oct. 27, 2010, James C. Cooper, 29, punched the 23-month-old girl 10 times and slammed her face first into a bed in a St. Charles hotel room.

As a result of the attack, the child suffered severe and permanent brain injuries and broken bones. Koch was present in the room during the beating but refused to stop Cooper’s actions and refused even to intervene on the child’s behalf, according to a news release from the Kane County State’s Attorney. Koch was not injured.

Koch was charged because she is legally responsible for the abusive acts of Cooper.

After she called 911 to report the girl’s injuries, Koch repeatedly lied to police about the cause of the child’s injuries and Cooper’s whereabouts, prosecutors said.

On March 30, 2012, Cooper was sentenced to 15 years in prison in exchange for a guilty plea to one count of aggravated battery to a child.

During Koch’s sentencing hearing, the state presented evidence that Koch repeatedly allowed the child to be in harm’s way and refused to remove the child from danger during their six-month relationship.

The child, now four, is permanently handicapped, developmentally delayed and cannot feed herself.

Before he announced the sentence, Judge Timothy Sheldon noted that throughout the court proceedings, Koch showed little if any remorse for her role in her daughter’s severe injuries.

“It is unconscionable to this court that a loving parent wouldn’t sacrifice everything to protect a child,” Judge Sheldon said.

Koch was sentenced to eight years in prison on the domestic battery charge and one year in prison on the obstructing justice charges. The terms are to be served concurrently.

According to Illinois law, Koch must serve at least 85 percent of the sentence.
