There’s new information into the fatal shooting at a party in Rimrock Saturday night. Yavapai County Sheriff’s deputies responded to multiple calls of a shooting on the four-thousand block of Top O The Morning in Rimrock at around 11 p.m. Investigators conducted multiple interviews of witnesses at the scene. Eyewitnesses say after an altercation at a party attended by three men, Rafael Zapata of Camp Verde was trying to leave with his companions. Partygoers surrounded his car and knocked out one of the windows. Zapata then fired a gun into the crowd, striking Efrain Arreola. At some point after Efrain was shot, his brother 22-year-old Edgar Arreola pulled out his Glock 9 millimeter pistol and opened fire, striking Zapata multiple times. After initially firing into the car, and after Zapata was clearly incapacitated and no longer a threat, Edgar circled the car to the other side and fired into the car again. Zapata and Efrain both died from their injuries. Edgar has admitted to the shooting. He was booked into the Camp Verde Detention Center without incident on a charge of first-degree murder for knowingly and intentionally shooting and killing Zapata.
