GARDEN CITY (AP) — A special prosecutor has announced that no criminal charges will be filed against the Hamilton County sheriff.

The Garden City Telegram reported Sheriff Richard Garza voluntarily placed himself on administrative leave following his arrest in September.

Scott City Attorney John Shirley said in an initial report that the incident stemmed from a “family matter” where no physical violence occurred. Shirley was appointed special prosecutor at the request of the Hamilton County attorney.

The Hamilton County Sheriff’s Office said Garza’s return to duty was effective Friday.
