FBI officials in Denver are expected to announce an increase in the reward money for information leading to the arrests of suspected cop killers and fugitives Alan "Monte" Pilon and Jason McVean.

The reward will add another $150,000 per suspect, said Cortez, Colo., Chief of Police Roy Lane.FBI officials in Denver had scheduled a 3 p.m press conference Tuesday, but a Denver FBI spokesman John Coonce would not confirm the reward increases when contacted by the Deseret News on Tuesday morning.

Currently, the reward being offered is $310,000 from Colorado, federal and local monies. The addition will bring the reward to $610,000.

Salt Lake City FBI special agent in charge David Tubbs, Denver FBI special agent in charge Frank A. LoTurco, Montezuma County, Colo., Sheriff Sherman Kennell and Lane are all expected at the press conference, Coonce said.

Pilon and McVean have been on the run since May 29, when, along with Robert Mason, after Cortez, Colo., police officer Dale Claxton was killed, triggering a 45-day manhunt that led police across the Four Corners region of southwestern Colorado and southeastern Utah.

In all, Pilon and McVean are suspected of killing one officer and wounding three others, including a San Juan County deputy sheriff.

So far, the men have successfully evaded police in three separate intesne search efforts. At one point more than 400 officers from 51 local and federal law enforcement agencies were involved in the search.
