Kleine said the woman wasn’t eager to testify but stands by her account of the February 2013 assault: that Cooper pulled over her and her boyfriend and had found marijuana in the car, and that Cooper ordered the boyfriend to take a walk and throw the marijuana in the lake.

The woman has told The World-Herald that Cooper took her to his cruiser, where he told her to remove her shirt and then exposed himself. She said she felt she had no choice but to obey.

The sex act lasted a few seconds, prosecutors say.

Attorney Horacio Wheelock, who represented Cooper with another Omaha lawyer, said his client was ready to go to trial next week to challenge the charge. However, he agreed to the no-contest plea for the sake of his wife and children.

“Cory Cooper is a family man, and he put his family first,” Wheelock said. “He did not want to put his family through a trial.”

Cooper was fired in May 2013 after a two-month investigation by Omaha police. Prosecutors said Cooper also falsified reports about where he was that night. His cruiser’s GPS system showed that he was at the lake.
