On the night of August 28, 2022, a backyard house party near 27th Street and South Mountain Avenue in Phoenix ended in gunfire. Xavier Paul Martinez, 21, had been celebrating his 21st birthday and was among dozens of partygoers when several shots were fired just after 1:30 a.m. Phoenix police, already responding to complaints about the loud party and possible gunshots, entered the yard and found three people struck by gunfire.

Martinez and another 21-year-old, Robert Puentes, were pronounced dead at the scene; a third person survived with non-life-threatening injuries. Homicide detectives investigated but initially identified no suspects. Two years later the case remained unsolved, and the victim’s family increased the reward for information that could lead to an arrest. The family say Xavier and Robert were not confrontational, leaving many unanswered questions about what happened that night.

If anyone was at that party or has information about who fired those shots, please come forward with what you know.
