Witness in US trial says Ethiopian immigrant tortured prison inmates in Ethiopia in 1970s

A trial witness has identified an Ethiopian immigrant living in Denver as a prison guard who tortured and killed inmates in Ethiopia in the 1970s.

The testimony came in federal court Thursday in the trial of Kefelgn Alemu Worku (kah-FEH'-lun ah-LEE'-moo WER'-koo). He's charged with immigration violations and identity theft.

Prosecutors say he lied on immigration forms when he denied committing political persecution.

If convicted, he faces up to 12 years in prison. He hasn't been charged in Denver with any crimes related to prison abuse.

Worku has acknowledged using a false name to gain admission to the U.S. but denies the torture allegations.

The Denver Post reports (http://tinyurl.com/m5bxre9 ) the witness claims she was an inmate at the prison and saw Worku shoot and kill two other inmates, teenage boys.
