Samuel Sena was 25 when he disappeared from Algodones, New Mexico, with his 48-year-old mother, Geraldine Sena, and 32-year-old John Santistevan. They were last seen on March 1, 2016, in a gray Ford F-150 pickup; all three were reported missing on March 17, 2016.

The abandoned pickup was found off Hagen Road, about 12 miles southeast of the San Felipe Casino. Investigators found the truck’s interior covered in blood and the vehicle full of bullet holes. Authorities concluded the trio had been killed, and their bodies were later recovered at a remote site where they had been burned and buried in a shallow grave, reportedly with a chemical accelerant.

Investigators tied the killings to criminal activity involving a stolen car ring and alleged fears the victims were informing or stealing drugs. Two men, Omar Flores-Castillo and Samuel Jiminez-Perez, were identified as principal suspects; Flores-Castillo is accused of luring the victims and allegedly shooting them with an AK-47. One suspect later led authorities to the burial site.

If anyone knew Samuel, his movements that week, or saw the gray Ford F-150, please share information.
