Beverly Mauck, 28, and her husband Brian were found shot multiple times in their home in Graham, Washington, on November 17, 2007, in what investigators described as execution-style killings. Friends and family told police the couple had no known enemies. A neighbor, 41-year-old Daniel Tavares Jr., told police he saw two men fleeing the Mauck home in a red pickup truck, but detectives later grew suspicious of his detailed account given the distance and darkness.

A bloody palm print on a doorjamb and signs someone had tried to clean the scene became key physical evidence. A background check revealed Tavares had been released from a Massachusetts prison after serving 16 years for the 1991 stabbing death of his mother. Under scrutiny, his account collapsed and he confessed, saying he had gone to collect a $50 tattoo debt, got into an argument with Brian, and shot both Brian and Beverly.

Daniel Tavares pleaded guilty to two counts of aggravated first-degree murder and received life without parole in February 2008. His wife, Jennifer Tavares, was charged with rendering criminal assistance for lying to investigators about his whereabouts the night of the killings. Did anyone in Graham at the time see or hear anything that could clarify what happened that night?
