Ketih and Elaine Dardeen were expecting a baby girl to add to their family and make their son Peter a big brother. But when Keith didn't show up for work, many got concerned and police made a visit to their home. That is where Elaine, Peter, and the newborn's bodies were found savagely beaten to death. Keith's body was discovered later, beaten and horrifically mutilated. Savannah goes through the timeline of these murders, the ongoing investigation that has lasted decades, and why the only viable suspect to come out of the investigation, serial killer Tommy Lynn Sells, may not be the culprit after all.
