The road near Kyle

On October 29, 2015, Alejandro “Tank” Vasquez was last seen by family members on American Horse Creek Road near Kyle, South Dakota, on the Pine Ridge Indian Reservation. He was 24 years old.

He has not been seen or heard from since. Not in the nearly eleven years since. Not once.

That is the public shape of the case: a young Oglala Lakota man, last seen by the people who loved him on a reservation road, and then — nothing. No confirmed sightings, no recovered belongings described in public, no arrests. The FBI is investigating his disappearance as a presumed death under the federal jurisdiction granted by the Major Crimes Act, which gives the bureau authority over serious crimes on reservation land.

Who Tank was

Public records about Alejandro Vasquez’s life are sparse — a reality common to missing-persons cases from Indian Country, where national media attention is thin and families often carry the search largely alone. He was 24, from Kyle, known as “Tank” to family and friends. He would be 35 years old today.

His case sits inside a larger crisis the federal government has finally begun to name: the epidemic of missing and murdered Indigenous people. The FBI’s renewed push on his case is part of Operation Steadfast Promise and Operation Not Forgotten, a surge of federal resources into unresolved violent crime in Indian Country.

The investigation

For years, the case moved quietly. Then, on September 15, 2026 — nearly eleven years after Tank vanished — the FBI’s Minneapolis Field Office issued a fresh public appeal, with a reward of up to $25,000 for information leading to the identification, arrest, and conviction of the person or persons responsible for his death.

“The FBI is dedicated to finding justice for all crime victims,” said Minneapolis Special Agent in Charge Christopher D. Dotson. “Even the smallest fact could help bring answers to a grieving family. There is no better time than now to come forward with information that will answer the outstanding questions about Mr. Vasquez’s disappearance.”

The appeal was covered across South Dakota media — the Rapid City Post, regional outlets — a rare burst of attention for a case that spent a decade in the dark. The FBI is asking anyone with information about the circumstances of his disappearance or death to come forward.

Theories: what might have happened

The FBI’s classification — a presumed-death investigation seeking “the person(s) responsible” — is itself the strongest public signal about what investigators believe: that Tank was killed, and that someone knows how.

Homicide. The FBI is offering a reward for information leading to arrest and conviction, language it uses when it believes a crime was committed. What undercuts a resolution: no body, no named suspect, no public forensic detail — eleven years of silence from everyone who was on that road.

What the silence suggests. On a reservation road, in a close-knit community, disappearances are rarely true mysteries to everyone. Someone saw something on American Horse Creek Road on October 29, 2015. The FBI’s bet — eleven years later, with $25,000 attached — is that the silence can still be broken.
