United States v. Ahrensfield
698 F.3d 1310
10th Cir.2012Background
- Defendant, a former APD officer, was convicted of obstructing justice under §1512(c)(2) after briefing Mr. Bryan about an undercover operation at Car Shop.
- The undercover operation, conducted by FBI and APD, targeted drug dealing and stolen-property activity at Car Shop, with Shawn Bryan as a potential leader.
- The operation relied on a confidential informant making controlled drug purchases to corroborate information and possibly secure cooperation from an arrested mechanic.
- Defendant disclosed the existence and details of the investigation to Bryan, contrary to need-to-know restrictions, to protect Bryan’s business connections.
- The disclosure occurred after officers learned Defendant’s son worked at Car Shop and after monitoring the informant’s controlled purchases.
- Following the disclosure, the task force halted some planned investigative steps, and Bryan took actions reflecting awareness of the investigation.
