The family of Don Lewis, the ex-husband of Tiger King's Carole Baskin, have launched a new appeal to find out what happened to him.

The businessman mysteriously disappeared in 1997 and was legally declared dead five years later, leaving Baskin to inherit most of his estate.

The Netflix documentary explored claims from rival Joe Exotic that she had murdered Lewis and fed him to their tigers - allegations she has strongly denied.

Baskin is now appearing on ballroom contest Dancing With The Stars and during her first appearance last night, Lewis's family paid to broadcast an advert asking for people to come forward if they know anything about his disappearance or Baskin's involvement.
