On the night of May 1, 2021, Mariceo Marz Negrete, 20, attended a crowded house party in Green Valley Ranch along North Odessa Street. Around 2:30 a.m. police were called after reports of gunfire; officers found two unresponsive men who were pronounced dead at the scene. The medical examiner later confirmed Negrete and another young man, Josiah Salas, died of gunshot wounds and their deaths were ruled homicides.

Investigators and prosecutors described the gathering as involving people linked to rival Denver gangs. A grand jury indictment and reporting identified Negrete with a group called CHI 30 and tied brothers Sergio and Andrew Rodarte to a rival group, Only The Family. The indictment recounts the brothers arming themselves, confronting Negrete on a back patio and firing multiple shots that struck both victims. Sergio Rodarte was arrested on June 2, 2021, and both brothers were indicted on first-degree murder and related weapons counts in October 2022.

Negrete is remembered in online memorials alongside Salas. Who in the community might have been at that party or has information about what happened on that patio?
