Some Oklahoma Highway Patrol troopers are being blamed for a paperwork problem that could impact several DUI cases.
Right now, a statewide investigation is underway.
A candidate for the state house of representatives was just served his DUI charge two years after the alleged crime.
John Gibbons says no breathalyzer test done and no blood test ordered, so he thought the ordeal was settled.
Now, Oklahoma County DA, David Prater says he anticipates there are dozens of similar cases.
"Essentially, now we know there is a problem, where before, we didn't," said OHP spokesperson, Lt. Betsy Randolph. "Now, we're going to make sure that we fix it."
Lt. Betsy Randolph says in June 2012 a trooper arrested John Gibbons on suspicion of driving under the influence.
But, according to her, he didn't file the proper paperwork and charges were never filed. Until now.
"We don't believe that it was malicious intent on his part, we believe it was a misunderstanding and a young trooper," said Lt. Randolph.
John Gibbons says while the timing of the misdemeanor DUI charge is suspect, he intends to remain in the race for House District 88.
"As far as we know, it's just this one case. Now there may be more," said Randolph.
Lt. Randolph says OHP Chief, Ricky Adams has initiated an investigation checking for problems statewide.
"Once that investigation is wrapped up, and that information is passed back on the chief, then he'll be able to make any additional recommendations, requirements, and get to the bottom of it," said Randolph.
The DA says this problem pre-dates the current OHP chief, calling it "inherited," and he's confident the chief will address the situation.
His office is working with OHP to identify other cases.
In Oklahoma, a DUI case can be filed up to three years after an arrest.
