In a Wednesday morning press release, the Coconino County Sheriff's Office said 37-year-old Reymond Martinez, 38-year-old Enrique Lopez, 17-year-old Abraham Rodriguez Delgado, and 36-year-old Manuel Bracamonte died in the Saturday crash.
Sheriff's officials recovered the victims' bodies Monday near Blue Ridge.
Sheriff's spokesman Jon Paxton says investigators are continuing to look into how the all-terrain vehicle veered off a forest road and plunged 400 feet.
Paxton says the four victims were from the Valley and had been on a camping trip in the Payson area.
The Saturday crash also sparked a 10-acre fire, which made it difficult for rescuers to get to the victims.
Bracamonte's sister released a statement to ABC15, saying:
Manuel was also known as Memo to close family and Manny to all his friends. He was our gentle giant, who loved everyone that he came across. He was an amazing son, brother, boyfriend, uncle and friend in every aspect you could think of. He could light up a room with his presence and his beautiful smile, with a great sense of humor.
