David Thomas Block, also known as Dave, was 35 years old when he was last known to have been seen in Washington, D.C., on May 1, 1995. He is listed as a White male with blond or strawberry-blond hair and blue eyes, about 5 feet 8 inches to 5 feet 9 inches tall, and approximately 154 pounds. Public case summaries describe him as having short, straight hair and no known scars or tattoos.
The Charley Project also notes that he had unspecified mental health problems, an important detail because it may have affected his vulnerability at the time he disappeared.
Although David’s last known sighting was in Washington, D.C., his case has strong ties to Canada. He was reported missing to police in Swastika, Ontario, and Canadian authorities have been identified as the investigating agency. Before the Washington, D.C. sighting, he was reportedly seen in Newfoundland in 1994. The later sighting in Washington, D.C., on May 1, 1995, appears to be the final publicly documented contact; after that date, he was not heard from again.
The available public information leaves many unanswered questions. Sources do not describe where in Washington, D.C., David was seen, who saw him, whether he was traveling alone, or what circumstances led him from Canada to the United States. Because so few details have been released, the timeline is limited mainly to the 1994 Newfoundland sighting, the May 1, 1995 Washington, D.C. sighting, and the report made to police in Ontario. The absence of additional public details makes the case especially difficult and underscores how painful prolonged uncertainty can be for those who knew and loved him.
David’s case is listed in NamUs as Missing Person case MP22333, and NamUs is a U.S. Department of Justice-supported national repository for missing, unidentified, and unclaimed persons information. The public NamUs listing identifies him as missing from Washington, D.C., with a date of last contact of May 1, 1995. The case information in the attached data identifies the investigating agency as Kirkland Lake OPP and lists DNA reference samples from two relatives as complete and associated with national CODIS, suggesting that family-reference DNA has been made available to assist with identification efforts if needed.
As of the available public sources reviewed, David Thomas Block’s disappearance remains described as a missing person case, with no publicly reported resolution. His story is one of a man last seen far from where he was reported missing, with limited public clues and decades of unanswered questions. The most compassionate reading of the record is that David remains a person whose life and identity matter, and whose family and community deserve answers after so many years.Last Seen: May 1, 1995
