A Sheridan police officer was shot and killed Tuesday while trying to serve a trespass warning on a man near the intersection of Fifth Street and Val Vista Street, leading to a continued standoff.

Sgt. Nevada Krinkee, a six-and-a-half year veteran of the department, was taken to Sheridan Memorial Hospital after the shooting, where he was pronounced dead, Chief Travis Koltiska said in a news release.

The suspect fled the scene after the shooting and was found in the area of Sixth Street and North Sheridan Avenue, where law enforcement established a perimeter once discovering he was barricaded inside, according to Koltiska.

“The entire department is shocked and saddened by this senseless act and appreciate all the thoughts and prayers from our community. Please respect the privacy of our brother Nevada’s family through this trying time,” Koltiska wrote.
