Steck joined the Sheriff’s Office in May 2021. Prior to that, he had worked for the Fort Dodge Police Department for 12 years.

Brady/Giglio requires prosecutors to disclose to defense counsel and defendants when an officer involved in the case has alleged incidents of misconduct that put their credibility into question.
