Possession Of Drug Paraphenalia
Probation Revoked-Fel


Note: We post all subjects who are taken into the jail. The majority of the time, this is due to a new arrest; however, sometimes subjects are transfered back to this facility from another facility, which would cause them to be re-posted. The charges listed above may be the result of the subject failing to appear for court, not necessarily a new charge. All subjects are presumed innocent until found guilty by the court of law.
