Jeff

Jeffrey Koval is a major character in the Marble Hornets ARG. He is listed in the intro as the "Camera and Editing" to Vincent's project.

He has little involvement at first, the first two entry only feature him during the opening. In Entry #63, he interrupts the beginning by messing with a little toy mouse as a joke. He also shows up in Entry #64, where he is the driver for the car that Vincent and Evan are pushing. Who the camera operator is on this scene isn't certain, nor important.

He is believed to be a Hollywood Undead fan, because in one of the episodes he is seen with an HU T-shirt.
