A sergeant with the University of Arizona Police Department who was charged in February for super-extreme DUI no longer works for the university.

Sgt. John McGrath's last day of employment was July 1, said Andrea Smiley, a UA spokeswoman.

Smiley said Tuesday because it was a personnel matter all she could confirm "is that he no longer is an employee with the university."

McGrath was on investigative suspension since the incident. On Feb. 1, McGrath, 27, was arrested after crashing a UA Police Department SUV into a traffic sign while on duty.

He was driving the marked vehicle when he hit a sign and cement wall on the Interstate 10 frontage road near Speedway shortly after 9:30 p.m., said Tucson Police Department Sgt. Pete Dugan shortly after the crash.

No one was injured.

Officers investigating the crash conducted a DUI investigation after noticing "signs and symptoms of possible impairment", said Dugan. McGrath's blood-alcohol content was .20 or greater.

He was charged with super-extreme DUI, three lesser DUI charges, failure to control speed to avoid a collision and criminal damage.

McGrath had worked for the UA Police Department since 2009. In 2013, he served a year tour in Afghanistan with the Army National Guard.
