(KNZA)--A Holton man convicted of fatally shooting his father has been sentenced to nearly 13 years in prison.

51-year-old Derrick Bohnenkemper was sentenced Friday in the death of his 73-year-old father, Galen Bohnenkemper, at the family's home in September 2018.

Following his release from prison, Bohnenkemper must serve 36-months on post release supervision and register as a violent offender for 15 years.

He pleaded no contest in December to a charge of second-degree murder.

His mother was able to escape the home and call 911.

Bohnenkemper surrendered to authorities following a more than five hour armed standoff, during which shots were fired at officers.

No officers were injured.
