The "Ghost Whisperer" alumna will play "the mother of an UnSub" who is "very protective and watchful over her son, whom she knows has some serious emotional problems," which chiefly include killing women who happen to look like his ex-girlfriend. To make this happy family even more appealing, rumor has it that Manheim's character has some skeletons in her own closet, too.
She'll appear in the two-part season premiere, which kicks off Wednesday, September 25 at 9 p.m. ET on CBS.
Also ahead for Season 9? Star Joe Mantegna will direct an episode!
"Criminal Minds" fans had a bit of a scare before the show was renewed for Season 9 -- cast negotiations for contract renewals went down to the wire, prompting worries that stars Kirsten Vangsness and A.J. Cook might leave the show. Thankfully, the entire cast was secured for another season and the show will continue to detail the investigations of the FBI's Behavioral Analysis Unit (BAU).
