Järnefelt is bookkeeper to the global underworld, an expert at managing finances and transferring money without drawing the attention of law enforcement. As such, he has become the premier facilitator for terrorists and criminal organizations alike.
He is considered to be a criminal myth by law enforcement agencies the world over, which maybe because he enjoys a measure of extra-legal protection. Given his meticulous attention to detail, this anonymity may also be due to his careful nature and the simple fact that he has never been caught with his hand in the proverbial cookie char.
ICA files show him fleeing within hours or even minutes ahead of raids, a fact which lends credence to possible connections within global law enforcement. The target has lead an unassuming yet comfortable life managing the finances of kleptocracies, terrorists and tyrants for decades (such as Karnac Holdings owned by Ekwensi and Caracas Trading owned by Delgado), at least since the late '60s. Files retrieved from Russia in the mid-'80s indicate that he may have been a part of the volunteer SS Wiking Brigade during the Second World War, but this link is inconclusive.
