Well known Elvis tribute artist Dana Mackay and his beauty queen girlfriend Mary Huffman were murdered inside their Las Vegas mansion.Dana headlined at the Dunes casino before moving to the Imperial Palace where he was the first Elvis to star in 'Legends in Concert'. He was a father and looking to leave the spotlight and start a landscaping business, supplying high dollar palm trees to the city of Las Vegas. Mary was a mother and former Mrs. Nevada.On October 30, 1993, Las Vegas Metro Police were asked to do a welfare check on Mackay after family and friends had not heard from the couple in days. When police arrived to the mansion named 'mini Graceland', the door was open, groceries were all over the floor and Dana and Mary were dead in a pool of blood.Police say the two were murdered, shot at close range multiple times.At first, Metro police thought the couple may have walked in on a 'burglary in process', however friends say nothing was taken from the home. Dana's best friend Danny Koker (of Pawn Stars, Counting Cars) says Dana always carried a file with him. The file was stolen the day of the murder. It's unclear what was inside.At the time of the murders, Dana had been in the middle of a legal dispute with his former landscaping business partner.No suspects have been arrested, no persons of interest have ever been named in the case.If you have any information you are urged to call Las Vegas Metro Homicide Cold Case Detail at 702-828-COLD.Podcast WEBSITE (Case Photos)http://www.truecrimedeadline.comPodcast SOCIAL MEDIA:https://twitter.com/CrimeDeadlinehttps://www.instagram.com/truecrimedeadline/https://www.facebook.com/TrueCrimeDEADLINE/http://www.youtube.com/c/TrueCrimeDEADLINESupport the show (https://www.patreon.com/posts/true-crime-lets-26942079?utm_medium=social&utm_source=twitter&utm_campaign=postshare)
