Jeremy Polk was a police officer in the Gotham City Police Department. After the Joker threatened to blow up a hospital, James Gordon ordered all hospitals evacuated, and Polk along with his partner Willy Davis helped evacuate Gotham General Hospital. Matilda, a nurse at the hospital, asked for their help moving someone, and Davis assisted her while Polk went outside to find a bus for Harvey Dent. He found one, and radioed Davis to bring Dent out, but Davis didn't respond. Worried, Polk went back into the hospital to find him, but instead found a nurse in Dent's room. He told the nurse to leave, but it turned out to be the Joker in disguise, who shot Polk and killed him.
