Authorities are looking for three men who escaped over the weekend from a northwest Missouri jail.

The Daviess County Sheriff's Office says the men crawled under a fence Sunday evening at the Daviess/DeKalb County jail.

The three include 57-year-old Carlos Sarmiento, a convicted murderer. He is described as Hispanic, 5-feet-9 inches, 140 pounds with brown hair and a tattoo of a woman's head with a sombrero on his left arm. He was convicted of killing a man in 2009 with a hammer.

The other men are 26-year-old Nicholas D. McCleary, who was being held on a previous escape attempt; and 34-year-old Timothy J. Baudour, who was being held for assault.

Officials say McCleary is 5-foot-7, 184 pounds with blond hair. Baudour is 6-foot-3 and 200 pounds. Both men are white.
