Prosecutor charged with assault by mattress

Turner County's State's Attorney has been charged with domestic assault.

Matt Olson, 41, was arrested on simple assault and interference with emergency communications charges Monday at his Centerville home, according to Division of Criminal Investigations spokesperson Sara Rabern.

The DCI was involved after the initial call due to conflict of interest issues, Rabern said.

Olson's wife filed for a temporary protection order the following day, writing that Olson first took away her phone, eventually giving it to her sister, who separated the fighting couple. She said Olson later "threw a king size mattress at me" before throwing it out the door and breaking the kitchen table.

She also accused him of cutting the house's electricity with a knife and twisting her arms behind her.

She'd filed for divorce the week before, alleging irreconcilable differences and extreme cruelty.

The temporary protection order was granted and will remain in effect until June 5.

Olson, 41, was elected to serve as prosecutor in the rural county in 2012 after working as a Minnehaha County Deputy Public Defender and a private defense lawyer.

Olson declined to comment on the case Friday. The maximum penalty for each misdemeanor charge is a year in jail.
