Mario Luis Delgado Jr., 47, was found dead in his trailer in Albuquerque on February 10, 2021. The Albuquerque Police Department determined his death resulted from a robbery that escalated into a fatal shooting.

Investigators say Samantha Shull, 34, who knew Delgado from a previous relationship, contacted him on February 9 and arranged to meet at his trailer. On the morning of February 10 Shull visited Delgado; Jeffrey Contreras, 27, then arrived armed and demanded money. Delgado pointed to his wallet, but Contreras shot him multiple times before fleeing with Shull. The suspects reportedly used Delgado’s bank card to make purchases at several Albuquerque stores.

Contreras was wanted by the U.S. Marshals Service in connection with an unrelated homicide in Roswell on February 5 and was later apprehended in Roswell, where he was already incarcerated. Shull was arrested in Roswell after a brief pursuit. Both were charged with murder, armed robbery, tampering with evidence and conspiracy; Contreras also faced a felon in possession charge and Shull was on probation at the time of her arrest.
