C. Thomas Howell as a serial killer

I'm sitting here watching Criminal Minds reruns on Ion, may the Lord forgive me. Anyway, it reminded me of some episodes from years ago, when C. Thomas Howell played a serial killer. The episodes were in seasons 4 and 5, and one in season 9... I don't know if I ever saw that one. Anyway, as a fan of The Hitcher (1986), I remember it was pretty interesting to see him play the killer, not the good guy. I thought he did a pretty good job, too. He tried to play it for laughs a LITTLE, but was mostly serious about it.

Here, this shows the episodes he was in:
