A convicted killer who escaped a Louisiana prison last month is now on the U.S. Marshal's Service list to most-wanted fugitives.

Officials say Keana Barnes escaped from the Louisiana Correctional Institute for Women in St. Gabriel on January 1.  She was serving a manslaughter sentence after being convicted of killing two men, a charge that was pled down from 2nd-degree murder.

In 2002, officials say Barnes stabbed james Robert Shepherd to death. In 2003, she fatally shot and killed Perry Jennings Jr. as he slept.

A reward of $25,000 is being offered for information leading to her arrest. 

The Marshals service says Barnes shaved her head and is possibly wearing wigs to hide her identity.  She is fluent in Spanish and has fled to Mexico in the past, authorities say. She has numerous tattoos on her left and right shoulders, chest, hand, back, and thigh.

Anyone with information on Barnes' location is asked to call Crimestoppers at 504-822-1111, or the U.S. Marshal's Service at 877-926-8332.
