Oklahoma soldier's clemency request denied

The mother of a U.S. soldier from Edmond, Okla., who was convicted of unpremeditated murder in a war zone says her son's clemency request has been denied.

Vicki Behenna says her son Michael told her Wednesday that the request was not approved.

Michael Behenna is an Army lieutenant who was convicted by a military court in 2009 of killing an unarmed Iraqi detainee in Iraq. Behenna said he shot the detainee after the man threw a piece of concrete at him then lunged for his gun.

Behenna was initially sentenced to 20 years in military prison. That sentence has since been reduced to 15 years.

Behenna continues to appeal his conviction to the Army Court of Criminal Appeals.
