A gathering on Top O The Morning Drive in Rimrock, Arizona, on the night of October 15, 2022, ended in two deaths after an argument escalated into gunfire. About 11:00 p.m., witnesses told the Yavapai County Sheriff’s Office that 27-year-old Rafael Zapata of Camp Verde was asked to leave, tried to drive away, and had his vehicle surrounded and a window broken. Zapata then fired into the crowd, and 27-year-old partygoer Efrain Arreola was struck and killed.

Efrain’s 22-year-old brother, Edgar Arreola, produced a 9mm pistol and shot at Zapata in the vehicle, wounding him multiple times; Edgar suffered a minor gunshot wound to his arm. Both Efrain Arreola and Rafael Zapata died at the scene. Edgar was arrested the next morning after admitting he shot Zapata, and was charged with first-degree murder on the allegation he continued firing after Zapata was incapacitated and no longer a threat.

Who at the party might have seen the first shots or the moments immediately afterward?
