A former Dawson County Sheriff's sergeant last week pleaded guilty to simple battery, nearly 18 months after he was accused of punching an inmate in the face during a scuffle at the jail. Shane Jenkins entered the plea Jan. 7 to Northeastern Judicial Circuit Juvenile Court Judge Lindsay Burton. In exchange for the negotiated plea, he was sentenced to 12 months probation on the misdemeanor charge that dates back to an incident on June 9, 2014.
