A supervisor warned in 2010 that Utah Highway Patrol Cpl. Lisa Steed, who is under investigation by her own agency, was frequently arresting people for driving under the influence of drugs who had no drugs in their systems.
The supervisor, Sgt. Rob Nixon, wrote a memorandum discussing the questionable arrests and implying Steed was falsely accusing drivers of impairment. Nixon wrote the memo after reviewing 20 of Steed's arrests for drug DUIs.
