A former Johnson County Sheriff’s deputy has been charged with unlawful sexual relations.

Vernon Finkenbinder was placed on administrative leave after he allegedly  inappropriately communicated with and touched a female inmate while in custody at Central Booking Facility between Sept. 23 and Sept. 25.

Following a criminal investigation and a professional standards inquiry, he was placed on administrative leave and later resigned. Investigators concluded the incident was isolated and that the security of the facility staff or other inmates was never in jeopardy, according to a press release from the sheriff’s office.
