The Seventh Circuit affirmed Deangelo Terrell Banks’s conviction for possessing a firearm while a felon in violation of 18 U.S.C. §§ 922(g)(1) and 924(a)(2). The court held that the district court did not clearly err in denying Banks’s motion to suppress the handgun or his motions for judgment of acquittal and a new trial. Regarding the suppression motion, the court applied de novo review to legal conclusions and clear error review to factual findings. First, the court found no clear error in the district court’s credibility determination that the arresting officer reasonably suspected a traffic violation (failure to signal) despite the officer’s inability to specify exact distances or blink counts; the officer’s familiarity with the area and testimony regarding street lighting were sufficient. Second, the court held that Banks forfeited his argument that officers unreasonably prolonged the stop to wait for a drug-sniffing dog because he failed to raise this specific ground in his motion to suppress as required by Federal Rule of Criminal Procedure 12(c)(3). Even absent forfeiture, the court found no error, noting that while the defendant was on the phone obtaining updated insurance information, the officers’ brief questioning did not delay those efforts. Third, regarding probable cause for the search, the court applied the standard from *Florida v. Harris*, holding that a certified drug-sniffing dog’s alert establishes probable cause regardless of whether drugs are subsequently found, and Banks failed to present evidence challenging the dog’s training or reliability. Regarding sufficiency of the evidence, the court reviewed the record de novo in the light most favorable to the prosecution to determine if any rational trier of fact could find the elements of constructive possession beyond a reasonable doubt. The court concluded that sufficient circumstantial evidence existed, including Banks’s exclusive control over the vehicle where the gun was hidden, his listing as a co-owner on the registration, his prior false statements to police claiming sole ownership of the car’s contents, and his incriminating jail phone calls suggesting he knew about the contraband. The practical consequence is that the judgment of conviction stands, and Banks remains subject to the sentence imposed by the district court.
