Atchison Atchison County authorities say a city police officer was shot and killed by a man who then shot himself.
Atchison County Sheriff John Calhoon says Sgt. David Enzbrenner was shot Friday afternoon while serving a nuisance order at an Atchison house.
He said the alleged shooter, 25-year-old Skyler Barbee, came "out of nowhere," fired at the officer and then shot himself.
Enzbrenner was a 24-year veteran of the Atchison police department.
Calhoon says it's not clear if Barbee lived at the home where the order was served. He says an investigation is continuing.
