Colby managed to take down the Sandman non-lethally (though the poor bastard has some broken ribs and a major concussion) and also managed to take the speedster alive, too, but their fight was something of a knock-down, dragged-out chase (narrative forthcoming) that ended miles outside of the city with Colby stuck with a busted up leg. So by the time he'd hobbled back to the convoy with the speedster over his shoulder, the fighting was mostly over.
