The San Diego County Sheriff's Department says it is investigating an accusation of inappropriate conduct against a top-level official.
The department on Tuesday confirmed the complaint against Assistant Sheriff Rich Miller but didn't provide details, citing the ongoing probe.
NBC 7 has confirmed with the department that Miller is using accumulated leave time until his retirement begins on March 2.
As an assistant sheriff -- one of three on the department's executive staff -- Miller ran the Sheriff's Detention Services Bureau, which oversees the seven county jails.
Miller joined the department in 1992, and was appointed an assistant sheriff in 2014.
He receives an annual salary of $317,000 in total pay and benefits according to Transparent California, a group that tracks public employee salaries.
