Four of the seven convicts who broke out of a Texas prison last month have been captured in Colorado.
A fifth inmate killed himself after barricading himself in a mobile home surrounded by authorities.
The whereabouts of the two other inmates are unknown.
The heavily armed inmates - including murderers, rapists and armed robbers - had puzzled and alarmed authorities by remaining together after bluffing their way out of prison on December 13.
The killing of a Dallas police officer 11 days later only increased fears that the inmates might want to go out in a blaze of gunfire.
The convicts had been in the Colorado area since about January 1, Teller County Sheriff Frank Fehn said. They kept a low profile in the sparsely populated community of Woodland Park, 50 miles south of Denver.
Authorities said a tip prompted by the television show America's Most Wanted led to the capture.
Among those arrested was George Rivas, 30, the suspected ringleader who was serving a life sentence for aggravated robbery and kidnapping. Investigators have portrayed Rivas as fearless and shrewd with a powerful hold over the others.
The Texas Department of Criminal Justice said Rivas had been captured with Randy Halprin, Michael Rodriguez and Joseph Garcia. Authorities said inmate Larry Harper killed himself inside the trailer.
Still missing were Patrick Murphy Jr, convicted of rape, and Donald Newbury, imprisoned for armed robbery. Sheriff Fehn said authorities had "no idea" where the pair might be.
