McGrath was arrested after he crashed his department-issued SUV into a wall on West Speedway Boulevard and the Interstate 10 frontage road. He was on-duty at the time of the crash. McGrath was charged with super extreme DUI because his blood alcohol level was almost four times the legal limit. A report by Tucson Police says the officer was given two breathalyzer tests, and recorded blood-alcohol levels of .308 and .317. The legal limit is .08
McGrath worked with UAPD since 2009, and was promoted to sergeant just over a year ago. He is also a member of the Army National Guard. He had just returned from a one-year tour in Afghanistan.
Separately, he faces multiple criminal charges in Pima County Superior Court related to the accident.
