HOLTON, Kan. (AP) - Prosecution of a Holton man accused of sexually assaulting several women has grown to $80,000.

The Topeka Capital-Journal reports that Jackson County attorney Shawna Miller decided early this year to seek a special prosecutor because charges against Jacob Ewing continued to grow, exceeding her resources.

Ewing has been convicted of raping two women and acquitted in the sexual assault of a 13-year-old girl. He's also awaiting trial on charges that include attempted rape and sexual exploitation of a child.

Former Shawnee County chief deputy district attorney Jacqie Spradling originally contracted for $20,000. Records the newspaper obtained through a records request show that fee was increased by $60,000 in March. Three commissioners said in a statement that the fee was a "concern."
