Alejandro Tank Pilar Vasquez, 24, was last seen in Kyle on the Pine Ridge Reservation on October 29, 2015, while visiting from Dodge City, Kansas. He left his brother Angel’s trailer near American Horse Creek that night and did not take a cell phone or debit card. Some reports say he was later seen knocking on the brother’s door on Halloween morning; Angel did not answer.

He is described as Lakota and Mexican, about 5 feet 7 inches, 185–200 pounds, with shoulder-length black or brown hair and brown eyes. At the time he went missing he was wearing a gray or charcoal shirt, plaid shorts with blue stripes, and white and black Nike shoes. Searches by land and air using ATVs, cadaver dogs, and an airplane turned up no evidence.

The Oglala Sioux Tribe Department of Public Safety and the Bureau of Indian Affairs handled the investigation. The tribe is offering a $25,000 reward. Rumors on the reservation and a belief by his father, Mario Vasquez, that he may have been murdered and buried have circulated; the family has criticized the level of follow-up on leads.

If anyone knew Alejandro’s movements in Kyle or saw him around October 29–31, 2015, please come forward with information.
