Delmar Dahl was 54 when he went missing from Houston, Texas, on November 16, 1990. The circumstances of his disappearance have never been fully explained, and there is little public information about his last known activities.

His case remains listed in missing persons databases, and the Texas Department of Public Safety continues to list him as an active missing person. Family and authorities have asked the public for help, but no significant leads have been reported and he remains missing.

If anyone knew Delmar, saw him in Houston around mid-November 1990, or has information that could help resolve his case, please come forward.
