|Appeared In||"Today I Do" (via flashbacks)|
Jeremy's early life is unspecified, other than he joined JTF-12, a team specializing in creates profiles for terrorists and help in their apprehension. Prior to that, he was a former worker for the German intelligency agency BND. The team's most notable mission was capturing Ian Doyle and his organization, which was done by sending one of its members, Prentiss, undercover as Lauren Reynolds. However, unbeknownst to the team, Jeremy was a mole for Doyle. Sometime after the mission's completion, the team disbanded for unspecified reasons, and Jeremy eventually became engaged to another member of the team, Tsia Mosely.
Today I DoEdit
When Doyle escaped from his North Korean prison in 2011, Jeremy took Tsia to Paris, France, during the events of Today I Do, likely to hide from him. However, this failed, as he was poisoned by a member of Doyle's organization, and his death was certified as natural causes, although Tsia told Prentiss that Jeremy was completely healthy at the time of his death. Meanwhile, Clyde Easter, the leader of JTF-12, was able to deduce Jeremy as the mole and also came to suspect Tsia of having some involvement, as she was engaged to Jeremy. Throughout the entire investigation on Doyle, Jeremy's status as the mole was unknown to Prentiss and the BAU, with suspicion falling on Clyde instead, but in Lauren, Clyde reveals to the BAU of his findings.
- In "Sense Memory", Prentiss possesses photos of her colleagues in JTF-12. For some reason, she doesn't have a photo of Jeremy.
