TUCSON - A Pima County Sheriff's deputy was fired Wednesday after rolling his patrol vehicle and authorities say he showed signs of impairment following the crash.

Authorities say Daniel M. Williams was off duty and wearing civilian clothing, but was driving his marked patrol vehicle at the time of the 4 a.m. rollover on Arizona 86 near Kitt Peak.

County officials say they will pursue civil remedies against the former deputy to recover the costs of the damaged vehicle and equipment.

Authorities say Williams was taken to University Medical Center where a blood sample was obtained and will be sent to the state Department of Public Safety for analysis. If Williams was impaired, they say the case will be sent to the county Attorney's Office to determine if charges will be filed.

Williams worked for the Sheriff's Department for little more than a year and was assigned to the Ajo District.

The department declined to discuss why Williams was terminated other than to say he failed to meet "end of probation standards."
