Summary based on the NamUs case record (MP60961) and 8 other sources
In the summer of 2002, a distressing and perplexing situation unfolded in Waltham, Massachusetts, involving a 39-year-old man named Jianhua Wu. The last known contact with Wu was on July 26, 2002. The sequence of events leading to his disappearance began on Monday, July 22, when he called in sick to his job at Boston Genome Therapeutics Corporation. When several days passed without any further communication, his concerned colleagues requested that authorities perform a welfare check on him. This request was made on Friday, July 26, marking the end of the work week.

Upon their arrival at Jianhua Wu's apartment, law enforcement found his vehicle parked outside, an ordinary sight that gave no immediate cause for alarm. However, a check of his residence revealed that Wu was not there. This discovery transformed a routine welfare check into the start of a mysterious missing person case. As days turned into weeks with no word from Wu, the official missing person report was filed with the Waltham Police Department on August 6, 2002, by which time he had not been seen or heard from in two weeks. From that point forward, a silence ensued, leaving his loved ones and investigators without answers.

The circumstances surrounding Jianhua Wu's disappearance remain an unsolved puzzle. He was an Asian male, stood at five feet six inches tall, and weighed approximately 101 pounds. He had black hair and black eyes. Despite the passage of time, very little additional information has surfaced to shed light on what might have happened to him after he called in sick to work. The case is a quiet one, marked by an absence of evidence or clear indications of his state of mind or intentions. The overview of the case is one of a man who seemingly vanished from his daily life, leaving behind his car and his residence, with no subsequent contact or credible sightings to explain his whereabouts.
