He passed what he thought was a yellow truck. Then he heard Hammond scream again. "When she screamed at me out the window," he said, "I put it in reverse and started chasing him. " Shafer chased the truck about a mile, he said, racing south on Clinton's 2nd Street, then turning west on Culvert Drive. But his car's transmission failed, Shafer said, and the pickup - maybe a 1969 or 1970 Ford - sped away. The truck may have had a decal of a water scene on the back window. Hammond has not been seen since. Police found her car in the parking lot that night, said Clinton Detective Damon Parsons.
