Berkeley resident and San Jose State University alum Hadari Darden, 28, mysteriously disappeared a week ago. His last apparent location was at the Skyline Plaza shopping center in Daly City, California, where he was reported for acting suspiciously. His mother, Hanifea Click, expressed concern over her son's behavior and stated that he appeared normal so officers allowed him to walk off. Since then, friends and loved ones have been searching everywhere for Darden who does not know anyone in the Daly City area and does not drive a car. Police have ruled out any evidence of foul play.
