IOWA CITY, Iowa (AP) – The assistant director of the Iowa Law Enforcement Academy will retire after facing months of criticism for making inappropriate sexual and threatening remarks to female cadets and colleagues.  A letter released Thursday to The Associated Press shows 71-year-old Michael Quinn will retire June 30. The move comes after Senate Democrats held him up as an example of personnel mismanagement by Republican Gov. Terry Branstad’s administration.

Quinn was the subject of reports by the AP last year showing that he was allowed to keep his job despite a state investigation that found he violated anti-discrimination and violence-free workplace policies.

The investigation found that he made remarks to cadets and employees about his testicles and his sex life and told one subordinate that he would “slit your throat” if she acted up.
