DENVER -- The man who police said was wanted for questioning in the shooting death of Broncos cornerback Darrent Williams will soon be released from custody, the man's attorney told 7NEWS.

Denver police arrested Willie Clark on a parole violation last Friday. Clark was one of three men wanted for questioning in the Williams murder case.

Clark's attorney, Michael Andre, told 7NEWS the supposed facts surrounding his client's arrest may be inaccurate and Clark could be released from custody as early as Wednesday morning.

Police said Clark was asked to provide any information that he may have in relation to the homicide of Williams, though Andre declined to comment if his client did in fact offer any information about the killing.

Photos and names of Clark and the two other men were circulated to prevent them from leaving the metro area and the state.

He said Clark should not be in jail because his arrest on a parole violation is the result of a mistaken identity.

Andre said last August Clark's cousin was pulled over in connection with driving without a license and driving while his license was under restraint. Andre said that because the cousin had used Clark's name in prior incidents with police, the citation led police to Clark and a potential violation of his parole.

The name on the ticket is Stephen Howard, Clark's cousin,

"My hope is on Wednesday morning I can prove the tickets were not his, and I hope at some point everybody will know Willie Clark was not involved in the shooting in any way," said Andre.

At least 14 shots were fired into the stretch Hummer that had just left a New Year's Eve party. Williams was struck once in the neck.

Police won't disclose whether they know the motive for the slaying but have said there was an altercation at the nightclub Williams attended prior to the shooting.

Clark served time for auto theft and had arrests on charges of felony assault, obstructing a police officer, drug possession and reckless endangerment.

There are reports that the drive-by shooting that killed Williams and injured two others was a gang-related attack.

Andre said Clark is not a gang member and had nothing to do with Williams' shooting. But he did confirm that Clark does know the owner of the white Chevy Tahoe, Brian Hicks, a known gang member.

"Mr. Clark denies any involvement in the Darrent Williams investigation. It is a very outrageous crime," said Andre. "It creates a great deal of public sentiment. I don't want to comment any further for my client's safety."

Andre said Clark and Hicks grew up in the same neighborhood. Clark's picture was not released because investigators may use it later for a photo lineup, 7NEWS investigator Tony Kovaleski said.

Forensic analysts are combing through the Chevy Tahoe confiscated in the Williams slaying.

Investigators said they started searching the high-usage areas of the vehicle such as the steering wheel and console. A Denver University forensic researcher said even if the suspects tried to clean the Tahoe, potential evidence is still there.

"It's virtually impossible to clean a surface in such a way that you're going to remove absolutely every bit of DNA," forensic researcher Dr. Phillip Danielson said.

Police found the white Tahoe three days after the shooting. It had been spray-painted black in what police said was an attempt to disguise the vehicle.

Danielson said a generic analyzer at DU mirrors the ones Denver police and the Colorado Bureau of Investigation use. He said it quickly generates a unique, numerical identification tag and it doesn't need much to work with.

"From an amount of body fluid or tissue that is smaller than the head of a pin," he said.

Danielson said police will likely find hair, saliva and fingerprints inside the Tahoe. While DNA is unlikely to point to just one person, Danielson said it should at least yield another set of leads detectives can work with.

"Current research is developing new technologies that will further improve this in the future," he added. "But right now we have some very valuable tools."

Danielson said Denver police could have useable DNA test results in 24 to 36 hours after they submit the samples. He added that the cold temperatures will perfectly preserve DNA evidence in a vehicle.

Denver police said they continue to seek information regarding this investigation and ask anyone with information concerning this case to contact the Denver Police Department or the Crime Stopper Line at 720-913-STOP (6737). A $2,000 reward is offered for information that leads to an arrest in the case.
