Criminal Minds Sneak Peek: JJ's Mom Spills a Dark Family Secret

Loading video...

Tonight on Criminal Minds (CBS, 9/8c), JJ’s mother Sandy pays a visit, and in doing so unpacks a bit of family baggage as well.

As seen in this sneak peek, Sandy (returning guest star Candy Clark) gives grandson Henry the 411 on his Aunt Rosaline, short of revealing exactly how it is that she wound up in a “better place.”

When JJ (A.J. Cook) gets wind of the bombshell Mom dropped, she has plenty to say. Or is she in part still in denial about her teenage sister’s suicide? Press play above, then render your verdict.

As for the Case of the Week, the BAU is stumped to determine the common denominator among male victims in Montana, making it difficult to profile the UnSub.
