mentalist owain yeoman amanda righetti 'The Mentalist' Season 6: Amanda Righetti and Owain Yeoman set to leaveThe coming unmasking of Red John on “The Mentalist” isn’t the only upheaval the show will face in Season 6. Two members of the regular cast will be leaving the CBS series.

Amanda Righetti and Owain Yeoman, both of whom have been with the show from the start, will depart late in the 2013-14 season, TVLine reports. Just how their characters, Grace Van Pelt and Wayne Rigsby, leave the show remains to be seen.

Last season’s “Mentalist” finale narrowed the list of Red John suspects to seven — and strongly implied Red John is someone Jane (Simon Baker) knows from his time working with the CBI. Rigsby and Van Pelt aren’t on the suspect list, but the Red John reveal could tie into their exit from teh bureau.

“The Mentalist” is scheduled to premiere Sunday, Sept. 29 on CBS.
