Jianhua Wu was 39 when he vanished from Waltham, Massachusetts, in late July 2002. He called in sick to his job at Boston Genome Therapeutics Corporation on Monday, July 22, and there was no further contact after that. Colleagues requested a welfare check on Friday, July 26; police found his vehicle parked outside his apartment but Wu was not at home.

A missing person report was filed with the Waltham Police Department on August 6, 2002, by which time he had been unseen for two weeks. He is described as an Asian male, 5 feet 6 inches tall, about 101 pounds, with black hair and black eyes. Little if any additional information has surfaced about his whereabouts or state of mind after he called in sick.

Does anyone have information about where Jianhua worked, who he saw in late July 2002, or any sightings after July 22?
