State v. Murphy, 293 P.3d 703

Murphy was speeding 79 mph in a 70 mph zone on I-70; traffic stop occurred at 6:49 a.m. with deputy Maschmeier issuing a warning.
Murphy was outside his car when the deputy returned his license and paperwork and shook hands before Murphy began walking to his vehicle.
Deputy asked Murphy if he had contraband and later sought consent to search; Murphy consented after a pat-down request.
Murphy provided keys to locked suitcases in the trunk; deputy conducted a search.
A total of 107.92 grams of crack cocaine was found in a fanny pouch in the spare tire compartment during the search.
Emergency lights stayed on throughout the encounter and search.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Whether the traffic stop became a voluntary encounter before consent	Murphy: stop extended; coercive factors present	Murphy: voluntary encounter under totality of circumstances	Yes, voluntary encounter; consent valid
Whether the deputy’s statements and actions established coercion	Murphy: “By the way” signals continuation of detention	Maschmeier: no coercive conduct; public setting	No, no coercion; factors support voluntariness
