Illinois Appellate Court
Criminal Court
Motion to Suppress
Court erred in granting Defendant's motion to quash his arrestĀ for DUI, after city police officer, acting within his jurisdiction, after an off-duty police officer from another city placed him in custody for improper lane usage. An off-duty police officer's use of a radar gun outside of his jurisdiction, before personally witnessing a driver commit other traffic offenses unrelated to excessive speed, will not taint subsequently developed probable cause to conduct arrest by officer acting in his civilian capacity. (HOLDRIDGE and SCHMIDT, concurring.)
