(KMZA)--Marshall County Sheriff Dan Hargrave has announced his retirement, effective June 1.

Hargrave is stepping down after almost 21 years in law enforcement—including 12 years as sheriff.

Hargrave said in a release that after 32 years total in public service, 12 of those with the Kansas Department of Transportation, he feels the time is right for retirement and on to his next journey.

The Marshall County Republican Party precinct committee will have to nominate a successor to fill his term, which expires in January 2021. The nomination will be forwarded to Governor Laura Kelly for confirmation.

Undersheriff Tim Ackerman will serve as acting sheriff during the interim. Ackerman filed earlier this year to run for sheriff's in this year's election.
