On the morning of January 31, 2017, Maria Desantiago, 28, and her partner Mark Reynoso, 34, were found dead outside their Mammoth, Arizona, home. Both had sustained multiple gunshot wounds from the same firearm and were discovered under a tree on the property by Reynoso’s father. A 911 call around 11:00 a.m. reported six gunshots and a woman’s scream, but an initial police patrol did not find anything and the victims weren’t discovered until shortly before noon.

The Pinal County Sheriff’s Office ruled the deaths a double homicide and said robbery did not appear to be a motive since the killer or killers did not seem to have entered the house. Investigators interviewed more than 50 people and concluded the attack was likely personal; they believe the suspect or suspects left in a midsize sedan or pickup truck. Maria was remembered as a hardworking mother of three who helped at the Reynoso family’s restaurant; the couple had a blended family of five children.

A reward is being offered for information that could lead to an arrest. If anyone knew Maria or Mark, or has information about the events that morning, please come forward.
