Nate Carlisle, in The Salt Lake Tribune, reported that: In a memo in 2010, "Sgt. Rob Nixon said he reviewed 20 of Steed's arrests for driving under the influence of drugs and found in seven of those cases, toxicology tests showed the driver had only a low amount of drugs, referred to as metabolite. Four other drivers had no drugs in their system", according to Nixon's memo. Yet in every case, Steed wrote reports claiming the drivers showed signs of impairment, such as dilated pupils and leg and body tremors. Nixon referred to "a pattern" of conflicting information between Steed's arrest reports and the laboratory results and said: "This is something that needs to be addressed before defense attorneys catch on and her credibility along with the DUI squad's credibility is compromised."
