There are still no results from the Wyoming Crime Lab’s tests on evidence collected in connection with the shooting incident last month involving a 19-year-old Jackson man, which left him hospitalized with a shoulder injury. Jackson Police Chief Todd Smith says the investigation into the alleged attack on Clancy Shaffer left officers with three theories about what took place, and what is found by analyzing the evidence should help narrow their focus to one of them. Smith says among those items was a large caliber handgun. Smith says technicians at the crime lab will analyze whether the signature strike of the firing pin of the gun matches the mark on the casing that was found at the crime scene. Smith adds that the shell casing will be also checked for fingerprints and DNA. Those lab results are due back this week. Meanwhile, Smith says police have not discounted the possibility that Shaffer may have been shot by someone he knows or by someone associated with an activity he may have been involved in.
