A party to a fatal Baraboo street fight pleaded guilty to felony murder Wednesday in Sauk County Circuit Court.

Christopher L. Nash, 39, of Baraboo, had been scheduled for a 10-day murder trial in October. But on Wednesday he entered a guilty plea to felony murder with substantial battery, as a party to the crime. The district attorney’s office may seek a penalty of up to 13 years in prison when Nash is sentenced Dec. 7.

Charges of intentional homicide and substantial battery were dismissed but read into the court record.

Another defendant in the 2015 incident, 32-year-old Matthew T. Harvey of Baraboo, reached a similar deal with prosecutors in July. He pleaded guilty to an amended charge of felony murder as a party to a crime. In what’s known as an Alford plea, Harvey maintained his innocence. Harvey is set for sentencing Thursday.

On Wednesday, Judge Michael Screnock ordered a pre-sentencing investigation in Nash’s case, to be completed by Nov. 17.

Four people were charged in the October 2015 fatal stabbing of Anthony Inman, 36, of North Freedom, and the severe beating of his friend, Anthony Peterson, 34, of Mauston. An altercation that began at a downtown tavern escalated into a deadly late-night confrontation at Walnut and Lynn streets.

Jae M. Robinson, 30, of North Freedom, was convicted of homicide and battery and sentenced to at least 28 years in prison.

No court date is scheduled in the case of the fourth defendant, Amanda N. Rotar, 25, of Baraboo, who is not said to have participated in the fight but is accused of driving the others away from the scene.
