SALT LAKE CITY — The ex-husband of longtime KUTV newswoman Shauna Lake was sentenced to probation Friday for assaulting Lake's co-anchor, Mark Koelbel.

Todd Nathaniel Marshall, 45, was ordered to complete 36 months of probation and pay restitution for Koelbel's medical expenses.

He pleaded guilty in March to aggravated assault resulting in serious bodily injury, a second-degree felony, and a reduced charge of burglary, a third-degree felony, as part of a deal with prosecutors. The burglary was originally charged as a first-degree felony.

As part of the deal, prosecutors agreed not to seek jail time and dismissed additional misdemeanor charges of criminal mischief and assault.

Marshall went to Lake's Holladay home on Dec. 9 at 9:30 a.m. to drop off clothing for their children. He then pushed his way into the house when the door was opened and confronted Koelbel, who was inside, according to charging documents.

Marshall came into the home saying, "Send out the tough guy," then began hitting Koelbel — who is identified in court documents as M.K. — and attempting to grab him around the neck, the charges state.

Addressing the judge during Friday's sentencing hearing, Koelbel described Marshall leaping on top of him, breaking the chair he was sitting in and bringing the two of them crashing to the floor with Marshall's full weight on top of Koelbel.

"The attack was unprovoked and premeditated," Koelbel said, accusing Marshall of hiding his car in the neighborhood and laying in wait outside Lake's home.

Koelbel explained that his rotator cuff was torn and his leg badly bruised during the assault, leaving him in great pain as he drove himself to see a doctor.

"I could not lift my arms, I was unable to turn the steering wheel of my car," he said.

Lake did not attend Friday's hearing.

Marshall apologized for the assault, calling his actions unacceptable and embarrassing and telling the judge he will have to live with the knowledge of what he did for the rest of his life.

"I am working every day to be better, my main focus is my two boys," Marshall said. "I am very sorry for my behavior."

Marshall's attorney, Wally Bugden, noted that Marshall has been proactive about making amends, completing an anger management course before the plea deal was even made.

In his statement to the judge, Koelbel noted that neither he, Lake, nor her children wanted Marshall to serve any jail time. Koelbel also asked that Marshall be required to abstain from drinking and undergo random testing for alcohol and drugs, though Bugden argued Marshall has no substance abuse issues and alcohol was not a factor in the incident.

"Your honor, alcohol had nothing to do with this. This happened at 9:30 in the morning," Bugden said.

As he handed down the sentence, 3rd District Judge Todd Shaughnessy granted Marshall's request to complete probation through a private company, and ruled he may complete a substance abuse evaluation to determine whether any alcohol restrictions should be imposed.
