Jake Polanski

 is a former co-worker of Dr. Will Zimmerman at the FBI.

{| While Will was investigating a mysterious pawn shop robbery / homicide case committed by two folding men in Old City, he asked Jake to borrow an FBI case file from a similar incident he had investigated in Austin, Texas back in 2005. In the Austin Federal case, the robbers gunned down three bank employees in cold blood then disappeared from the vault (stealing half a million dollars in gold) where the only means of escape was via a small 9-inch square ventilation shaft. According to Dr. Helen Magnus' memory, the scenario Will proposed didn't win him many 'points' within the agency.

After concluding the Old City case, Will returned the Austin files to Jake at a subway station just under the deadline for them to be returned. As they chat, Jake says that it's a shame Will still continually gets put down by others in law enforcement for his different way of seeing things. Jake was one of Will's very few supporters, claiming that he's never meet another agent with more raw potential; an admission Will thanks him for just before leaving.
