( CNN ) -- Three teens admitted to police they attacked two homeless men who were found dead in Albuquerque , New Mexico , on Saturday , police said . The boys -- 15 , 16 and 18 -- used bricks and a metal pole to kill the men , according to a criminal complaint accusing each of them of two counts of murder . A judge set bond at $ 5 million each during a hearing Monday . All three are being prosecuted as adults , although the two youngest are being held in a youth detention center . The 15-year-old told an investigator that the trio `` randomly '' attacked homeless people throughout Albuquerque over past year , including more than 50 people since moving to the neighborhood several months ago , the complaint said . The bodies of two men were found on mattresses in a field across a street from the home where two of the boys lived , according to the complaint . A third man told police he managed to escape the late night attack and he recognized the teens despite the T-shirts covering their heads . The youngest boy said he `` was very angry over breaking up with his long-time girlfriend '' when he went with the older boys to `` mob '' the men , an investigator said in a sworn statement . The boy explained that `` 'mob ' meant they were going to attack them and rob them , '' the detective said .
