Peter was last seen departing from his family's residence in Berkeley, California at approximately 11:00 a.m. on August 28, 1995. He told his brother that he planned to take a bus to Cody's Bookstore. Peter never returned home and has not been heard from again. His wallet was discovered after his disappearance, but his identification cards were missing. He had just passed his driver's test, but hadn't gotten his license yet; it arrived in the mail a few weeks after he disappeared. The driver of the AC Transit bus 43, in Berkeley, claims Peter asked him directions to Montclair, California on the day of his disappearance. He appeared to have a prearranged meeting with an unidentified teenage boy whom the bus driver also saw. The boy was 16 to 18 years old with blond hair, well-dressed, accented speech. The boy has never been identified and the bus driver's sighting about Peter has not been confirmed. A cab driver claims he drove a young man fitting Peter's description, and a teenage girl, to the airport to catch a Southwest Airlines flight shortly after Peter disappeared.
