Police spokesman Simon Drobik said Sunday that 18-year-old Alex Rios, a 16-year-old boy and a 15-year-old boy are being held in Bernalillo County detention facilities.
According to a criminal complaint, Rios has been charged with multiple counts including two for murder.
Drobik says the younger boys will likely be charged with murder as adults.
Police say officers responded to a 911 call Saturday around 8 a.m. reporting two bodies in a field.
Investigators say all three suspects were located at a nearby house.
The complaint says the teens admitted to investigators that they beat the victims using their hands, feet, bricks, sticks and a metal pole.
