Detective Keith L. Williams, 34, was killed on November 13, 1989, while transporting a prisoner in Queens, New York. Williams was a member of the Queens District Attorney’s Squad and was riding with Detective Richard J. Guerzon and a prisoner, Jay Stoney Harrison, on the Grand Central Parkway in Elmhurst when Harrison produced a stolen firearm and opened fire from the backseat.

After the shooting Harrison attempted to flee in the detectives’ vehicle, then ran on foot toward LaGuardia Airport. A ten-hour manhunt ended with his capture at a woman’s residence in East New York, Brooklyn. The killings prompted changes in how prisoners are handled and transported.

If anyone knew Detective Williams or was in Elmhurst or near the Grand Central Parkway that day, can you share what you remember?
