A former deputy in suburban St. Louis is accused of using his position to steal prescription drugs.

The Jefferson County Sheriff’s Department said Friday that its former deputy, 35-year-old Michael Filsinger of Arnold, faces four counts of felony stealing, one count of misdemeanor stealing and one count of misuse of official information by a public servant.

The sheriff’s office says Filsinger accessed the department’s report management system to identify reports involving prescription drugs.

While on and off duty, he allegedly went to people named in those reports falsely claiming to be a detective following up on previous investigations. Officials say he then stole some of those medications.
