David Thomas Block, 35, was last seen May 1, 1995, in Washington, D.C. Canadian authorities are handling his case because he was reported missing to police in Swastika, Ontario. Before that, he had been sighted in Newfoundland in 1994.

At the time he disappeared he was described as a white male, 5 feet 8 inches to 5 feet 9 inches, about 154 pounds, with short straight blond hair, blue eyes and a 2.5-inch scar on his right forearm. He had documented mental health issues that might have brought him to the attention of authorities. The Kirkland Lake Ontario Provincial Police are listed as the investigating agency, and his case appears in NamUs as MP22333 and in the National Centre for Missing Persons and Unidentified Remains as 2006019499.

Few details are available about the circumstances of his disappearance and he has not been seen or heard from since May 1, 1995. Does anyone have information on David’s movements in 1994–1995 or recall seeing him in Washington, D.C., Newfoundland or northern Ontario?
