Justin Thurber was returned to the Cowley County jail late last week, after spending more than a month undergoing a mental evaluation at the Larned State Hospital.
On Saturday morning, authorities say the accused killer used his shoe to bust an overhead sprinkler in his cell.
The Cowley County's Sheriff's Department says the most significant damage was to the sprinkler. Thurber's cell and a nearby room also sustained minor flood damage.
Thurber was temporarily moved to a nearby cell and restrained while the damage was cleaned-up. Officials say it's possible he may be charged with the damage to the cell.
In September, a judge ordered Thurber to undergo a competency evaluation before allowing his capital murder trial to move forward. Jury selection was scheduled to begin in October.
Another court hearing is scheduled Dec. 16th when the results of Thurber's mental evaluation are expected to be released. If Thurber is found competent to stand trial, jury selection will likely begin in January -- two years to the month after it's alleged he kidnapped, raped and killed Cowley College student Jodi Sanderholm.
