Mark Margolis, known for his unique acting roles in “Breaking Bad” and “Better Call Saul,” passed away this week. He was 83 years old.

Margolis died in New York City at Mount Sinai Hospital on Thursday after a battle with a brief illness, according to his son, Morgan Margolis, CEO of Knitting Factory Entertainment.

Margolis is best known for his role as Hector Salamanca — nicknamed “Tio” — in “Breaking Bad” and the show’s prequel, “Better Call Saul.”

In the shows, Salamanca is the uncle of three notable characters, Marco, Leonel, and Tuco — all of whom are involved in drug trafficking. Salamanca was handicapped and largely communicated by ringing a bell on his wheelchair.
