The Mesilla Files did not begin with a single discovery. It grew from recordings, photographs, research reports, field investigations, personal journals and documents created decades apart.
This timeline tracks the investigation as the evidence has been discovered and released by TMF.
Some entries are historical documents. Others are modern investigations. Connections shown here do not necessarily mean the events themselves are connected.
This record will be updated as new material becomes available.

Early TMF Investigation
Theodore Orion Xyler—known throughout the surviving material as TOX—turns over an unusual collection of documents, photographs, recordings and research material.
Dylan Carrillo and Spencer Clifton begin examining the collection.
What initially appears to be a collection of unrelated Southwestern stories begins producing recurring names, locations and symbols.
STATUS: Investigation ongoing
SOURCE: TOX Archive
Material in the archive repeatedly leads back to Mesilla, New Mexico, and the surrounding desert.
Four names begin appearing with unusual frequency:
Sheriff Tomas Ortega.
Father Miguel Serrano.
Lawrence Jackson.
Captain Voss.
The men apparently knew one another.
A surviving photograph even shows the four sitting together in a Mesilla bar during the 1930s.
Three left records behind.
Voss did not.
QUESTION: Why does Captain Voss appear throughout other people's records while leaving almost nothing in his own voice?
Recordings and surviving records belonging to Sheriff Tomas Ortega begin revealing the life of the Mesilla lawman before his unexplained disappearance in 1936.
Early material describes ordinary law-enforcement problems.
Later recordings increasingly reference unexplained desert reports, unusual incidents and Ortega's growing concern about Captain Voss.
Ortega eventually begins making trips into the desert alone.
STATUS: Audio archive being released
SOURCE: TMF Audio Archive — The Saga of Sheriff Tomas Ortega
The personal records of Lawrence Jackson provide another perspective on early Mesilla.
Jackson was a businessman, publisher, filmmaker and collector who became increasingly interested in stories circulating through the region.
One diary describes Jackson's growing suspicion that Captain Voss was not aging normally.
An old photograph apparently showed a man identical to Voss years earlier.
After Voss learned about the photograph, it disappeared.
QUESTION: Who was Captain Voss?
Surviving parish recordings made by Father Miguel Serrano provide yet another record of Mesilla during the early twentieth century.
Many of Serrano's earliest recordings were damaged or lost.
A substantial number from the 1920s survived.
Among otherwise ordinary parish matters are accounts of people reporting unusual events in the surrounding desert.
One surviving recording contains separate reports involving stones arranged deliberately into unusual shapes.
Serrano also remembers seeing a similar marking years earlier.
The recording that might have documented that earlier event is missing.
STATUS: Archive being examined
SOURCE: The Serrano Chronicles
Additional photographs apparently depicting Captain Voss are discovered.
Images believed to date from the 1930s, 1968 and 1987 appear to show the same man with remarkably little change in apparent age.
One early photograph places Voss near a remote structure bearing an unusual marking later identified in TMF records as the Scorpion Mark.
No satisfactory explanation has been established.
STATUS: Unresolved
Documents reveal references to an organization identified as the:
CONTACT AND TRANSITION AUTHORITY — CTA
The discovery is unexpected because surviving material places CTA activity considerably earlier than previously believed.
One document appears to date CTA activity to 1958.
Amy Wright later confirms that CTA existed decades ago and says her father helped organize it.
She promises additional information.
Questions remain.
STATUS: Active investigation
QUESTION: Contact with whom? Transition to what?
The TRC Research Center begins examining the Mesilla–El Paso region as it may have existed approximately 50,000 years ago.
The research indicates a dramatically different environment—cooler and wetter, with grasslands, woodland, lakes and large Ice Age animals.
The purpose of examining such a distant period initially seems unrelated to much of the historical archive.
TRC argues that some questions may require looking much farther into the past.
STATUS: Research continuing
SOURCE: TRC Research Report
Geographic research identifies an unusual pattern with Mesilla near the center of an apparent X connecting several areas associated with TMF investigations.
The locations extend through New Mexico and into northern Mexico.
Whether the pattern is meaningful or coincidental remains unresolved.
STATUS: Hypothesis only
SOURCE: TRC Research
Journalist and TMF investigator T.J. Clayton receives access to portions of the White Sands area while investigating historical material.
Records connected with Captain Voss are discovered.
The best preliminary dating places some of the material at approximately 1935.
The discovery further complicates the known timeline of Voss's activities.
STATUS: Under investigation
SOURCE: T.J. Clayton / Special Archive Session
Clayton follows information from an old NMSU acquaintance into remote desert country south of Deming, New Mexico.
Unusual stone arrangements are reported near the Mexican border.
The formations appear deliberate.
Their purpose is unknown.
STATUS: Field investigation
T.J. Clayton receives an urgent message from his hunting acquaintance regarding something discovered in remote desert country south of Deming.
Clayton travels into northern Mexico and photographs five unusual stone formations.
Viewed together, the formations appear to resemble:
A — V — A — R — A
Clayton cautions that they may not be letters at all.
He had previously traveled through what he believes was the same general area and does not remember seeing the formations.
He does not claim that they recently appeared.
He photographs the site without disturbing the stones and sends the material to TRC.
Clayton reports an unexpectedly strong feeling of uneasiness while examining them but explicitly identifies that reaction as subjective rather than evidence.
STATUS: Preliminary Field Observation

OPEN QUESTION: What, if anything, does AVARA mean?
Dylan receives a message from an old NMSU friend now working with a genetic research group at a university in Florida.
His friend has encountered a newly released announcement from an Italian genetics research center.
He jokes that it reminded him of some of Dylan's old theories about human heritage.
Then Dylan sees the date.
Approximately 50,000 years ago.
SOURCE: Communication received by Dylan Carrillo
The Valdombra Center for Human Genetics and Ancestral Research announces results from a twelve-year genetic investigation.
Researchers say they have identified genetic evidence of a previously unknown ancestral population contributing to modern human ancestry approximately 45,000–55,000 years ago.
The population is provisionally designated:
Ancestral Population V-50
Its unusual genetic signature is designated:
V50-HG17
Study leader Dr. Alessandro Venturi says he is prepared to stake his professional reputation on the evidence that the unidentified population existed.
His interpretation is considerably more controversial.
Venturi describes his “least impossible” explanation as an advanced population of Homo sapiens possessing genetic characteristics that researchers would not expect to find together during that period.
Researchers cannot presently identify where the population lived.
STATUS: Independent research — no established connection to TMF
IMPORTANT: TRC has presented no evidence establishing a relationship between V-50 and its own 50,000-year research.
Theodore Ray Mercer reads the Italian announcement.
His reaction is considerably less cautious.
Mercer questions why everyone appears reluctant even to discuss the possibility that the unexplained genetic ancestry could have a nontraditional explanation.
He openly uses the word others seem determined to avoid:
Aliens.
Mercer does not claim that V-50 represents extraterrestrial ancestry.
Instead, he challenges Dylan and TRC to state plainly what they know, what they don't know and what possibilities they are actually considering.
His message to Dylan is simple:
“Truthful answers. Understandable answers.”

Who was the unidentified ancestral population?
Letters, symbols or coincidence?
Why does he appear not to age?
Who or what was the Contact and Transition Authority contacting?
What happened before his 1936 disappearance?
Are the old parish accounts relevant to Clayton's discovery?
Why are independent investigations repeatedly pointing toward the same period?
