People v. Padgett
In People v. Padgett, 932 P.2d 810 (Colo. 1997), two officers observed Padgett and a companion cross a street. When they got out of their vehicle and asked Padgett if they could speak with him, "Padgett continued walking" away from them. Id. at 812.
An officer then "called out a second time," and Padgett "reluctantly" walked back to where the officers were, an encounter that led to the discovery of contraband on his person. Id.
In upholding the suppression of that contraband, the Colorado Supreme Court relied in part on the officer's second request, finding this encounter to have been an investigative stop unsupported by reasonable suspicion, not a consensual interview.
