A 23-year-old man has been convicted of attacking a 19-year-old woman at a rest stop off Interstate 29 near Onawa.
A news release from the office of the Monona county attorney says Mark Bitzan was accused of taking the woman into a stall in the women's restroom, threatening her with a knife
and sexually assaulting her.
The crime occurred on Dec. 17, 2010. A jury convicted Bitzan on Tuesday. His sentencing has not been scheduled yet.
The news release says Bitzan was convicted in 2006 of a sexual assault in Natrona County, Wyo.
