TUCSON -- The owner of a Tucson gun store where former U.S. Rep. Gabrielle Giffords' husband purchased a semi-automatic rifle has canceled the transaction.
Doug MacKinlay said Monday that a full refund was sent to Mark Kelly via express mail because the former astronaut didn't plan to keep the AR-15-style rifle for his personal use.
Kelly bought the gun March 5 at Diamondback Police Supply, saying he wanted to show how easy it is to buy an assault weapon. He planned to turn it in to Tucson police.
MacKinlay tells The Arizona Daily Star that he terminated the transaction Thursday before Kelly could take possession of the firearm.
Giffords was among 13 people wounded in a January 2011 shooting outside a Tucson supermarket that left six others dead.
