Summary based on the NamUs case record (MP26846) and 4 other sources
Douglas Kimberly Armstrong, a 19-year-old man from Palo Alto, California, was last seen on April 1, 1975. On that day, he abruptly left his parents' home in the 4300 block of Miranda Avenue and never returned. His family described this behavior as uncharacteristic, noting that Armstrong typically maintained contact with loved ones. At the time of his disappearance, he was wearing a long-sleeved lavender, blue, and white-striped shirt, a brown corduroy three-quarter-length coat, and blue jeans, along with black plastic-framed eyeglasses.

Douglas had graduated from Henry M. Gunn High School in 1973 and was known by the nickname "Kim." Despite some reports suggesting that he might have traveled to the East Coast, there has been no verified information about his whereabouts since that day. Speculation about him being imprisoned in Mexico under an assumed name has never been confirmed. His case remains unsolved after decades, and investigators continue to encourage anyone with information to come forward.

The Palo Alto Police Department is handling the investigation, and Douglas' case is listed in missing persons databases such as NamUs.
