DES MOINES, Iowa (AP) — An Iowa Division of Narcotics Enforcement special agent has been charged with falsifying the signature of a Polk County judge on a search warrant document. Jonathan Borg turned himself in to the Polk County jail on Tuesday for processing. He is free after posting a $5,000 bond. On Friday, the Iowa Attorney General’s office charged the 39-year-old agent with felonious misconduct in office.

Court documents allege that Borg falsified the signature of Polk County District Court Judge Christopher McDonald on a returned search warrant in February in connection with a narcotics investigation in Des Moines. Borg’s attorney, F. Montgomery Brown says Borg is cooperating with the investigation, denies the allegations, and has entered a not guilty plea. A trial has been scheduled for Aug. 12.
