Leslie Mayer of Hutchinson is convinced the Lyon County Attorney’s Office withheld evidence that would have helped her late son Travis avoid at least some of the 56 months in prison he served after being found guilty of aggravated battery of a law enforcement officer at a 2017 trial. The withheld evidence, she believes, included police body cam footage, and she has made strenuous efforts, including filing a complaint with the FBI, to prove the Lyon County Attorney’s Office should have disclosed the footage to Travis’s defense attorney. Yet, it now appears there was no body camera footage to disclose.
