Though it has been nearly six months since an off-duty sheriff's deputy was cited for speeding in the Northwest Valley, a Maricopa County Sheriff's Office investigation into the matter is still pending.

Peoria police in February ticketed Jason K. Parker, of Surprise, for driving 96 mph in a 45-mph zone in his Chevrolet Corvette.

According to police reports, the 26-year-old deputy was also cited for failing to provide proof of insurance.

Sheriff's Office officials said the agency would conduct an internal probe into the citation after they heard about the incident, and declined to comment until it was complete.

A series of information requests to the Sheriff's Office about the case, which began on March 10, went unanswered.

However, in a July 21 e-mail request for information, Capt. Paul Chagolla answered, "case still pending."

Speeding was also apparently an issue while Parker was on the job, according to the deputy's annual evaluation, which was obtained by The Arizona Republic under the state Public Records Law.

Parker's supervisor reported in Parker's Nov. 7, 2007, performance review that the deputy had been involved in two vehicle accidents in the past year, citing speed as a factor.

In the off-duty speeding incident, a Peoria officer on his way home reported seeing a Corvette speeding near Grand and 111th avenues. The officer caught up to the vehicle in El Mirage, where he called for backup, police said.

The car's driver was identified as Parker.

State law states that speeding becomes a criminal offense if a driver exceeds the speed limit by more than 20 mph. However, a copy of the Peoria police citation shows that while Parker was cited for "excessive" speed, it was changed later to simple speeding.
