Wikileaks quotes a U.S. Embassy cable which states the government set Dwyer and his fellow paramilitary gang members up in order to attack opponents of the Evo Morales government.

Bolivian investigators later claimed to have found email correspondence linking one of the men shot to Istvan Belovai, a former Hungarian military intelligence officer who defected to the U.S. in 1990 and later became a CIA agent.

But United States diplomats say this was a hoax and Dwyer was lured to his death as part of a plot by Bolivia's own intelligence services aimed at Morales opponents.

The diplomatic cable from La Paz released by Wikileaks says Dwyer was hired by disguised Bolivian intelligence agents and set up to mount a phony terrorist campaign.
