On March 23, 2024, 19-year-old Joseph Andres Martinez, a Hispanic male, was shot and killed during a large party at the Victory Grange event center on Tower Road in Aurora, Colorado. A fight involving Martinez and the ex-boyfriend of his then-current girlfriend reportedly escalated; witnesses said another person was directed to attack Martinez. While Martinez stood against a wall, a teenager approached, produced a handgun, and fired a single shot that struck him in the chest. Panic and multiple additional gunshots sent partygoers fleeing, and vehicles were seen speeding away from the scene.

Officers found Martinez gravely wounded and he was pronounced dead at a local hospital less than an hour later. Another person sustained non-life-threatening injuries. Investigators obtained an Instagram video of the shooting and an invitation to the party that helped identify a suspect; witnesses viewed the video and a photo lineup that included a driver’s license photo. Does anyone have information about who attended that party or saw what happened that night?
