From the Northeast Intelligence Network, we find the full text of the al Qaeda Communique on the beheading of American Paul Johnson (whom they refer to as Paul Marshall), translated from Arabic. Marshall was Mr. Johnson's middle name):

Source - Voice of Jihad publication Voice of the Mujahideen in the Arab Peninsula Subject: Killing of the American Paul Marshall Date: 1/5/1425 [6/18/2004] News Report No. 14 on the beheading of the American prisoner Paul Marshall Thanks to God, and prayer and peace on His messenger, our Prophet Mohammad and His companions and followers.

As promised, and after the expiration of the ultimatum set by the Mujahideen to the Devils in the Saudi Government, the Mujahideen from the Fallujah Detachment beheaded the American prisoner (Paul Marshall). This infidel received his fair punishment in this world before moving to the other world. He got to taste some of what the Muslims suffered from the Apache American helicopters that grilled them with their fire flames, embers, and missiles. The American infidel was one of four people in charge of the maintenance and system development of those helicopters.

With His help, we shall continue to fight the enemies of God, watching them everywhere, guided by the light of His book, and the law of His prophet, prayer and peace on Him. We shall put out the fire in the chests of the Believers in Palestine, Afghanistan, Iraq, the Arab Peninsula, and other Muslim countries. We shall keep humiliating the Polytheists and Blasphemers’ soldiers until the erection of a government ruled by the Shari’a, the Justice, and Attawhid. In our journey, we shall not pay attention to put the traitors down, or listen to the cawing of the failures that were disclosed by God in this incident. They shouted in fury for the capture and killing of a Christian soldier while they did not have the courage to say one word of truth in support of the oppressed Muslim prisoners who are being tortured at the hands of the adorers of the cross, and the devils of Abu Ghraib, Al Ha’er, Guantanamo, Al Ruways and other prisons.

As for the Americans and their supporters, blasphemers and criminals who ganged up in their coalition for a war on Islam, this action is an example and a lesson for them to be sure that those of them who came to our country will receive the same fate and God is our guide to the path of righteousness.
