But because police don’t seem to have a ton of leads in the case, they say they’re doing all the can to try and track the man down.UPDATE: A contractor working on a boat in found Clark’s body in a lagoon near the Bellingham waterfront.Police say it appears as if Clark was in the water for a few days as his body is badly decomposed.
