Two "credible" tips about the possible whereabouts of two suspected cop-killers are located in San Juan County, Utah, but Cortez Police Chief Roy Lane said Monday that he’s waiting before he get his hopes up.

"I’ve gotten to where I don’t believe anything until it’s been checked out," Lane said Monday. Lane said he forwarded the information to the San Juan County Sheriff’s Office, but he did not know when or if they would be pursued. Lane refused to elaborate on the details of the tips.

The tips were the two most reliable reports received by the staff of "America’s Most Wanted," a television program that aired a segment Saturday about the search for Alan "Monte" Pilon, 31, of Dove Creek, and Jason Wayne McVean, 27, of Durango.

Montezuma County Sheriff Sherman Kennell, who has been involved in most of the searches for Pilon and McVean, said Monday that he had not heard about the two tips.
