Pamela Cordes Tucker, 64, and her husband Denie Oliver Tucker, 68, were found dead in their Crossville, Alabama home on Pea Ridge Road on September 11, 2015. Investigators determined both had been shot the previous day: Pamela three times and her husband once in the back. The scene suggested a robbery; Pamela’s purse was emptied in the living room and her husband’s wallet was found nearby, and several safes at the home had been opened while one containing a large sum of cash was missed.

Police tied two men to the killings: Jeffery Lee McKelvey, 46, of Decatur, and Henry Martin Pyle, 54. McKelvey had allegedly approached Denie Tucker at a Cracker Barrel with a story about a family emergency and was given money and a business card that included the Tucker home address. McKelvey was arrested in November 2015 and Pyle was later arrested; in August 2016 Pyle pleaded guilty to murder and agreed to testify against McKelvey, receiving a life sentence. At trial, evidence against McKelvey included a pair of Pamela’s earrings he pawned in Birmingham and his fingerprint on a storm door at the Tucker home.

Did anyone in Crossville know the Tuckers well enough to recall strangers asking about their address in late summer 2015?
