Fairfax City's animal warden, who was charged in August with leaving the scene of an accident after a traffic incident, was found not guilty yesterday by a Fairfax County Circuit Court jury.

Louis C. Frank, 43, of 3405 Andover Dr. was arrested on the felony hit-and-run charge after Ok Hyun Choi, 24, was struck by a vehicle on Oak Street in Fairfax City the night of Aug. 9.

According to court testimony, Frank was trying to pull his pickup truck onto Oak Street when Choi drove by in reverse, almost hitting his vehicle. Choi approached the truck and became involved in a physical altercation with Frank's two passengers, at one point clinging to the neck of the man sitting next to the open window in the front seat, according to testimony.

Frank then drove away, and Choi "fell or jumped" and was struck by the truck, according to testimony. The prosecutor maintained that Choi suffered neurological damage.

Frank's attorney, Warren W. McLain, maintained throughout the two-day trial that his client was not aware that his vehicle had struck Choi. Frank was off duty at the time of the incident but was placed on administrative leave pending the outcome of a review.
