for all the suspicion of steven's friends, the murder case against harvey morrow was rather weak. no evidence sufficient to prove that harvey shot steven and dumped his body in the ocean. >> we were looking for steven's dna on the boat, knowing that his death was caused by a gunshot wound. it was pretty obvious that there should be something that said this is where it was. >> reporter: but there wasn't. no blood, no gun. no significant fingerprints. what they needed, couldn't find, was something that put the two men together on the far side of catalina island, where that current would have caught the body, carried it round to the spot where boaters saw it floating face-down in the water. they hunted everywhere for harvey's gps, but never found it. months went by, harvey sitting in the jail. no luck for the investigation now. and then a phone call. it was the commandant of harvey's yacht club. >> he says, i found a handheld gps in the library of our club. >> reporter: the commandant told them someone in the club had found the gps, wrapped in a napkin and hidden in the back of a club
