FORT SMITH, Ark. (AP) — An attorney for a former Sebastian County jailer convicted of sexually assaulting two inmates says the man and county are immune from a federal lawsuit filed by the inmates.

Little Rock attorney Jason Owens says in court documents that 65-year-old Leon Wilson Wood and the other defendants are protected from being sued because of multiple types of legal immunity.

Wood pleaded guilty to two counts of third-degree sexual assault in February and was given a four-year prison sentence, with 16 years suspended. In June, the inmates sued Wood, the county, the judge in the case and other county officials in U.S. District Court in Fort Smith.

The suit claims the defendants knew about constitutional violations in the jail but were indifferent about the situation, didn't implement requirements of an agreement between the county, jail and U.S. Justice Department and failed to properly train, supervise and monitor jail staff.
