Baird was a hypnotist for a travelling carnival where he mentally enslaved Leo Horne. After a year of being Baird's prisoner he eventually broke free enough to kill Baird and buried him in a field, however this left a permanent blood red mark on his shoulder. He bought a nostrum from Massu, a carnival salesman, who promises that it "will restore the flesh" and when he uses it, it removes the blood stain, but regenerates the body of Baird, who seemingly strangle Leo to death.
