The least talked about jihad attack on American soil.

LITTLE ROCK, Ark. (AP) — The man charged with killing an Army soldier and wounding another in Little Rock is now claiming to have killed a man in Nashville, Tenn., in 2006.

Abdulhakim Muhammad makes the claim in a letter to Pulaski County Circuit Court Judge Herb Wright.

The letter doesn’t say who was killed — only that it was a man who robbed and terrorized elderly Muslims and Muslim women. Police in Nashville told the Arkansas Democrat-Gazette they don’t know what killing he’s talking about.

Prosecutors and defense attorneys say they were not aware of the letter.

Muhammad is charged in Little Rock with capital murder in the June 2009 shooting death of Pvt. William Long outside a recruiting center. He has said the shooting was in retaliation for U.S. military action in the Middle East.
