Christian Lorenzen was indicted on charges in a DUI arrest last year.

A state trooper arrested him in April  and charged him with driving under the influence, possession of handgun while under the influence and speeding in a work zone.

As the accused officer once had this current DUI charged dismissed and now is again facing the same charge after a grand jury indictment.

Back in November of last year, Chattanooga General Sessions Court Judge Clarence Shattuck dismissed the case after Lorenzen's defense attorney pointed out it was one of those handled by a TBI lab employee who was terminated after he mixed up two blood alcohol tests.

But the judge advised Lorenzen the case could be brought back if the grand jury indicts him which they have.

Lorenzen's case of one of 2,800 compromised after it was revealed TBI agent Kyle Bayer had compromised the test results.

Some 320 of those 2,800 cases are Hamilton County DUI's. At this point it's unknown whether Lorenzen has an attorney.
