Police in the San Diego suburb of La Jolla are trying to figure out who stole the statue of the Lorax, based on the character from the Dr. Seuss book, from the garden of Seuss’ widow, Audrey Geisel. Law enforcement officials speculate it may be a theft, perhaps for the value of the heavy statue melted down, or a prank. The statue was made by Geisel’s sculptor daughter, Lark Grey Dimond-Cates, for her step-father. Dr. Seuss’ The Lorax is currently in theaters, where the Universal Pictures release has grossed nearly $180 million after four weeks in release. Dimond-Cates made two copies of the statue; the other is in a museum.
