A letter purportedly written by a "person of interest" in the fatal shooting of Broncos cornerback

Darrent Williams

says he fired shots into Williams' limousine when he was killed on New Year's Day 2007.

The Rocky Mountain News said yesterday it obtained the letter, which carries the signature of Willie D. Clark. Denver police have said Clark worked for an alleged gang leader who owned the SUV believed to have been used in the shooting.

The newspaper published a redacted excerpt of the letter reading, "[Blank] might say somethin stupd talk to law enforcements about the death of D-Will [Williams]. [Blank]) seen me withe gun + shoot out the whip [car]."

Williams, a 24-year-old cornerback and former Oklahoma State standout, was killed when his rented limousine was sprayed with bullets minutes after leaving a New Year's party at a downtown Denver club.

Clark was arrested on a parole violation after Williams' death and is now in jail awaiting trial on drug charges. Neither he nor anyone else has been arrested or charged in Williams' slaying.

The News said it obtained the letter from a Denver man who claimed he intercepted it while serving time in a prison where Clark was held. The newspaper said that man also turned the letter over to law enforcement.

The News said it was not identifying the man because he could be in danger for providing the letter.

An independent handwriting analyst hired by the News said the signature on the letter matched previous letters written by Clark to the newspaper and to a federal judge. In one of those letters to the newspaper, Clark denied he was involved in Williams' death.
