A multimillion-dollar collection of art from icon Andy Warhol has been stolen from a West Los Angeles home. A housekeeper for art collector Richard L. Weisman noticed on Sept. 3 that several pieces were missing, though police say there was no sign of forced entry and nothing else in the home was disturbed. The thief left several Warhol works untouched. Weisman left the house the day before the housekeeper made the discovery. An anonymous source has offered a $1 million reward for information leading to the recovery of the paintings. Weisman was a friend of Warhol's and commissioned the silk screen Athletes series in the late 1970s.
