Criminal Minds - Season 6 - Casting News - Daniel J. Travanti to Guest

Hill Street Blues star Daniel J. Travanti is headed to the other side of the law: The Emmy and Golden Globe-winning actor will guest-star as a serial killer in upcoming episode of Criminal Minds, TVGuide.com has learned exclusively.

Travanti will play Mr. Mullens, a crotchety 75-year-old whose brutal murders 20 years ago earned him the nickname "The Butcher." Now suffering from Alzheimer's and depending on the live-in care of his adult son, Mullens crosses paths with Hotch (Thomas Gibson) and the rest of the Behavioral Analysis Unit when he comes out of retirement in a desperate attempt to reprise his violent past — a past he can no longer remember.

Travanti, 70, is best known for playing the intense, somber Capt. Frank Furillo on Hill Street Blues, a role for which he earned two Emmys and Golden Globe. He also starred on ABC's short-lived Missing Persons in the early '90s and more recently guest-starred as President Richard Mills on Fox's Prison Break.
