Does this make sense to you? Again, a Fairfax County Cop’s gun just “Went off”July 7, 1998 A Fairfax County police officer's gun went off during a scuffle yesterday morning, wounding a woman who had just led police on a long chase along U.S. Route 1 through Prince William and Fairfax counties. After the chase finally ended in a Mount Vernon shopping center, Diana Elizabeth Tyler, 38, of Stafford County, refused to get out of her car. While Fairfax officers pulled her from the car, one officer's gun went off, police said. The bullet struck her in the neck, police said. Police wouldn't give the name of the officer whose gun discharged and would only say that he was holding the gun in his hand at the time. The department's internal affairs division is investigating.
