Detailed Case Breakdown

Gerald Thomas Clifford Missing Person Case: 1972 San Francisco Disappearance

Brief Case Summary

Missing: March 17, 1972
Official last known location: San Francisco, California
Age when missing: 19
NamUs: MP43073
Status: Missing; no publicly announced resolution located as of September 11, 2026

Gerald Thomas Clifford disappeared during a cross-country trip in 1972. The official NamUs information places his last known location in San Francisco on March 17, but later family-related information indicates he may have last been heard from while somewhere in Colorado during his trip west. His girlfriend reportedly believed he successfully reached San Francisco and left a note with her roommates.

Gerald Thomas Clifford Disappears During Cross-Country Trip

Gerald Thomas Clifford was 19 years old when he disappeared on or around March 17, 1972. His case is officially associated with San Francisco, California, where NamUs states that Gerald was last seen on that date. He has never been located, and his disappearance remains unresolved more than five decades later.

Later information shared by people advocating for Gerald provides a more complicated account of his final journey. According to a family-related account shared publicly in 2026, Gerald was hitchhiking across the country from Medford, Massachusetts, to San Francisco, California, where he planned to visit his girlfriend. The same account says he was last heard from on or around March 17 while somewhere in Colorado.

Did Gerald Reach San Francisco?

There is evidence suggesting that Gerald did make it to California.

According to information attributed to his girlfriend, she was away from the state when Gerald arrived in San Francisco. She reportedly said Gerald reached the city and left a note with her roommates before disappearing. The publicly available information does not disclose what the note said, when Gerald supposedly left it, who specifically saw him, or whether investigators ever obtained the note.

This creates one of the central questions in the case. NamUs records Gerald’s last contact and location as San Francisco on March 17, 1972, while later family information indicates he was heard from in Colorado on or around March 17. Both statements cannot necessarily describe Gerald’s location at exactly the same time, and the available public records do not resolve the discrepancy.

Gerald Clifford’s Description and Identifying Features

Gerald was described as a white male standing approximately 5 feet 8 inches to 5 feet 11 inches tall and weighing between 180 and 220 pounds. He had blue eyes and longish, curly brown hair and may have had a beard when he disappeared.

Gerald also had unusually distinctive identifying characteristics. He had been born with an extra thumb, which was removed at birth, leaving a scar near the knuckle of his right thumb. He also had a scar near the outside corner of his left eye. These characteristics could be particularly important when comparing his case with unidentified-person records.

The Missing-Person Report Was Apparently Never Filed in 1972

One of the most significant revelations surrounding Gerald’s disappearance concerns what apparently happened after his family realized he was missing.

In a family account circulated publicly in 2026, Gerald’s niece said her grandparents repeatedly tried to have a missing-person report filed. According to her account, however, a report was apparently never entered at the time. She said she discovered the problem while looking for Gerald’s original report in 2018 and was unable to find one.

Gerald was subsequently entered into the National Missing and Unidentified Persons System. His NamUs case was created April 13, 2018, nearly 46 years after his disappearance. His current NamUs identification is MP43073.

The decades-long reporting gap may help explain why comparatively little contemporaneous investigative material about Gerald is publicly available today.

Gerald’s Family Continues to Seek Answers

The family account shared in 2026 indicates that Gerald was the oldest child in his family and that his mother had younger siblings, including a sister who remembered him fondly.

Gerald’s niece described him as especially kind toward his youngest sister and expressed hope that the surviving members of the family could finally receive answers about what happened to him. Because Gerald disappeared in 1972, memories, photographs, letters and information from people who knew him in Massachusetts, Colorado or California could potentially be valuable even if they initially appear insignificant.

Recent Information and Continuing Interest in the Case

Gerald’s case received renewed public attention in 2026. In April, information attributed to Gerald’s family was shared in an online missing-person awareness post and subsequently discussed by researchers on Websleuths. The information introduced the Colorado portion of Gerald’s journey and the account that he was hitchhiking from Massachusetts to California.

Discussion continued through the summer of 2026. On August 1, a Websleuths participant identifying himself as John Chaplain stated that he had known Gerald while growing up in West Medford, Massachusetts. He said he did not know what happened to Gerald but had wondered about the disappearance for years. That statement is a community contribution and has not been independently verified as an investigative lead.

As of September 11, 2026, I located no public announcement from the San Francisco Police Department stating that Gerald has been found or that his case has been solved. The case continues to appear in current missing-person discussions, and NamUs #MP43073 remains the principal national case reference located during this review.

What Happened to Gerald Thomas Clifford?

Several important questions remain unanswered.

It is unclear exactly when Gerald left Massachusetts, what route he hitchhiked across the country, who may have given him rides, where in Colorado he was when contact was reportedly made, and precisely when he supposedly arrived in San Francisco.

It is also unclear what Gerald wrote in the reported note left for his girlfriend, who actually saw him in San Francisco, where he stayed after arriving, whether he intended to return to Massachusetts and whether investigators were ever able to reconstruct his travels.

There is currently no publicly verified evidence establishing that Gerald was the victim of homicide. His case should therefore continue to be described as an unsolved missing-person case unless law enforcement releases information establishing otherwise.

How to Provide Information

The San Francisco Police Department Special Victims Unit handles missing-person investigations. Anyone with information concerning Gerald Thomas Clifford can contact the SFPD Missing Persons Unit. SFPD also accepts information through its non-emergency number and anonymous tip system.

Even information dating back to 1972 could potentially matter, particularly from anyone who knew Gerald in West Medford or Medford, Massachusetts, encountered him while he was hitchhiking west, knew where he was staying in Colorado, or saw him after his reported arrival in San Francisco.
