A Chicago-area man suspected of taking part in the killing of a teenager who was beaten and shot before his body was set on fire has been added to the FBI's 10 Most Wanted Fugitives list.

Luis Macedo of Oak Lawn is charged with first-degree murder in the 2009 slaying of 15-year-old Alex Arellano.

Authorities contend Macedo was a member of the Latin Kings street gang that confronted the teen as he walked down a street. They have said the boy told the group he was not affiliated with any gang and then was beaten with bats and chased into an abandoned building. He was shot and his body was set on fire.

Other suspects have been arrested, convicted and sentenced to prison terms.
