Adrian Charles Reuwsaat was 69 when he disappeared from Sioux City, Iowa. He was last seen on November 1, 2002, and his family reported him missing on November 3. At the time he went missing he may have been driving a red 1991 Nissan pickup truck; neither Adrian nor the vehicle has ever been found.

When last seen he was wearing a green sweatshirt, a blue denim jacket, and blue jeans. Investigators have classified his case as an involuntary disappearance, indicating the possibility he was taken against his will, but few additional details have been released and the case remains unsolved.

If anyone has information about Adrian’s movements in Sioux City around November 1, 2002, or about a red 1991 Nissan pickup truck, contact the Sioux City Police Department.
