Robert Puentes, 21, was killed in a mass shooting at a large house party near 2700 E. South Mountain Avenue in Phoenix during the early morning hours of Sunday, August 28, 2022. At about 2:18 a.m. multiple gunshots were fired in the backyard; Robert and his 21-year-old cousin Xavier Martinez were both struck and died at the scene. The cousins had recently celebrated their twenty-first birthdays and were described as having an inseparable bond.

Despite many people attending the party, investigators have struggled to identify those responsible. By early September 2022 no arrests had been announced and no suspects publicly identified. The family held a vigil and has urged anyone who witnessed the shooting to come forward with information.

If anyone was at that party or has information about what happened in the backyard that night, please share what you know with Phoenix police.
