A Glasgow man was sentenced Monday to 12 years in prison after admitting to assaulting two performers from a Scottish music group at the end of the annual Glasgow Highland Games Festival this summer.

James Everett Null II, 42, was formally sentenced by Barren Circuit Judge Phil Patton, having earlier pleaded guilty to two counts of second-degree assault.

Null was arrested at Barren River Lake State Resort Park, the site of the annual festival, at 12:56 a.m. June 6 after an investigation determined that he had stabbed two people with a folding knife during an altercation in the park’s cabin area.

The two victims were James “Jamesie” Johnston and Colin Walker, members of Albannach, a Scottish tribal drumming band that performs at several Scottish heritage festivals each year in the United States and Scotland.

According to court records, Johnston, 38, was stabbed in the right thigh and the right side of his chest, resulting in a punctured liver. Johnston was treated at University of Louisville Hospital, and the remaining band members performed several shows without him as he continued to recover after his release from the hospital.

Walker attempted to intervene in the altercation and was also cut in the chest, according to an incident report by Detective Erik Salman of the Kentucky State Police, but he refused treatment.

Barren County Commonwealth’s Attorney Karen Davis said that Null had worked with the band during prior visits to the Highland Games, but was not working with the band in any capacity at this year’s festival.

“The way I understand it, Mr. Null had come to the cabin, they were all cooking out and enjoying the conclusion of the Highland Games,” Davis said. “Apparently, he partook of too much alcohol and when he was asked to leave, that’s when it all kind of went down.”

The Barren County Sheriff’s Office and Barren River Lake State Park rangers assisted in the investigation.

A grand jury originally indicted Null on one count each of first-degree assault and second-degree assault.

In October, Null accepted a plea agreement reducing the first-degree assault charge to second-degree assault. The terms of his agreement call for Null to serve consecutive six-year sentences on each count.

Court records include a victim impact statement written by Johnston in which he described how he was affected by the attack.

“I now feel wary of being in large crowds, which has made my job as an entertainer more difficult,” Johnston wrote in the statement. “I was always accessible to those attending shows, however I now feel I am less trusting of people.”

Davis said that members of Albannach kept in regular contact with her office during the case, even taking a break from touring to drive eight hours to meet with Davis about a week before the case had been scheduled to go to trial.
