(CNN) -- Authorities are hunting for three convicted murderers who escaped from a Kingman, Arizona, prison on Friday night.
The Arizona Department of Corrections and the Flagstaff police said on Saturday that the three disappeared from a medium-security facility and are considered to be armed and dangerous.
State and local authorities are searching for the men, who were discovered missing after the 9 p.m. count in prison. All three suspects were serving time on murder convictions.
Early Saturday morning, Flagstaff police said the suspects abducted two people at gunpoint and then released them at a local truck stop in the Kingman area.
The three escaped inmates are: Tracy Province, a 42-year-old white man who is 6 feet 1 inches tall and weighs 184 pounds with brown hair and blue eyes; Daniel Renwick, a 36-year-old white man who is 5 feet 11 inches tall and weighs 190 pounds with brown hair and hazel eyes; and John McCluskey, a 45-year-old white man who is 6 feet 1 inches tall and weighs 160 pounds with brown hair and blue eyes.
Province is serving a life sentence for murder and armed robbery. Renwick is serving 22 years for second-degree murder and McCluskey is serving 15 years for second-degree murder and other charges.
