"As Houdini said, my brain is the key that will set me free."
Luke was born with fetal alcohol syndrome to an alcoholic mother who died in childbirth. His father then gave him up for adoption because he didn't feel he was competent enough to raise a child. When he was six, he was also abandoned by his foster mother, Sylvia Walker, who feared that he would harm her own newborn child due to his mood swings. He grew up in the system, in and out of foster homes and institutions. He resented his abandonment and began his killing spree with the ultimate goal of killing his first foster mother.
Luke comes to New York to perform in his famous show entitled "Death Becomes Me". When members of his crew start turning up dead, the CSI team is called to investigate. Stella is able to trace skin DNA off a magic wand found at the scene of assistant Austin Cannon's death to George Clark, who proves to be Luke's biological father. He is arrested while trying to drown his foster mother in a re-enactment of Harry Houdini's famous straight jacket escape trick.
Luke targeted the people in his life who abandoned and betrayed him. The ways in which he killed his victims corresponded to the stunts he performed in "Death Becomes Me". This included sawing a woman in half, burning a man to death and attempting to drown his mother.
