David Rossi (Joe Mantegna) will get a special birthday present from a person from the past when "Criminal Minds" season 12 returns in January for episode 4. It's no other than Thomas "Tommy" Yates (Adam Nelson), a serial killer who appeared in "Criminal Minds" season 7, episode 22 titled "Profiling 101."
The official synopsis for "Criminal Minds" season 12, episode 9 reveals Rossi will receive a phone call from his serial killer nemesis, Tommy Yates also known as "The Womb Raider." Workaholic Rossi is doing a lecture on Profiling Course on his birthday when Yates calls him to reveal the location of his latest victim.
Yates is one of the criminals with the most number of victims in the series. He claimed to have killed 101 victims in 17 years over the West Coast. He targets women with high-risk or low-risk lifestyles. He alternates his targets from women with low risk to high risk lifestyles for unknown reason.
He is currently in jail so it's up for the BAU agents to solve how he got his hands on another victim. Maybe it's a flashback or it could also be that he got away. "Profiling 101" ended as Rossi visited Yates in prison. Yates gave him his own version of birthday card, a note with a name of his victim with the note "Happy birthday. Love, Tommy," before singing him an eerie birthday song.
Meanwhile, previous spoilers revealed that Jane Lynch is set to appear as Spencer Reid's (Matthew Gray Gubler) mother in the upcoming episodes of "Criminal Minds." In the midseason finale, Reid received a phone call from his mother and it was reported that later episodes will reveal the past of Mrs. Reid.
"Criminal Minds" season 12, episode 9 titled "Profiling 202" is written by Virgil Williams, the same writer who wrote "Profiling 101," and directed by Rob Bailey. The episode will air on Jan. 4, at 9 p.m. ET on CBS
