A preliminary investigation has revealed Drug Unit Detectives were conducting an investigation and attempted to stop a black Volkswagen Jetta. The Volkswagen Jetta failed to stop and drove westbound on Chambers Road at a high rate of speed. At the time, an unmarked police Dodge Caravan, driven by Detective Antonio Valentine and occupied by another St. Louis County Police Detective, responded to the area, travelling eastbound on Chambers Road more than a mile away from the attempted traffic stop. Meanwhile, the black Volkswagen Jetta, continued speeding westbound on Chambers Road, where the two vehicles converged near the intersection of Crete Drive. Evidence at the scene demonstrates the Jetta crossed the center lane and struck the Dodge Caravan. Responding units attempted lifesaving efforts to treat Detective Valentine, who ultimately was transported to an area hospital where he later succumbed to his wounds.
