Police looking for two young men in connection with the mysterious fatal shooting of a Tacoma man have released surveillance video of the pair.

David Watson, 45, was apparently shot as he sat in his pickup truck outside a convenience store near South 56th Street and South Lawrence Street early Sunday morning, the Tacoma News Tribune reported.

Watson then drove away and drifted off the road into a park about two blocks away. The sound of the pickup's engine revving alerted neighbors, who called police, the TNT said.

Mark Fulghum told the newspaper that shooting didn't appear to be a robbery or a drug deal.

The surveillance video shows two men in the convenience store parking lot. One shot shows them running from a pickup truck.
