DNA Taken From 2 Men In Williams' Investigation

(CBS4) DENVER Police investigating the shooting death of Denver Broncos cornerback Darrent Williams have been scrambling to get evidence from possible suspects in the case. That evidence includes DNA.

Investigators have taken DNA samples from two men to find out if those samples tie them to the shooting scene, CBS4 Investigator Brian Maass reports.

Maass first reported on one of the possible suspects Sunday night. The other 'person of interest' is Willie Clark, 23, the man who has been in jail for weeks on unrelated charges.

Clark's attorney confirmed that police took saliva from his client for a DNA sample. The lawyer believes officers are trying to link Clark to the Chevy Tahoe thought to have been used in the Williams' shooting.

A lawyer not involved in the case told CBS4 getting a judge to approve an order for samples ranging from DNA to fingerprints, known as a 41-1 order, is relatively easy.

"They conceivably found fingerprints in the suspect vehicle and they're trying to put people in the vehicle or exclude them as people that were in the vehicle," said Phil Cherner, a local attorney.

Multiple sources told CBS4 that police also obtained DNA from a second person investigators believe was in the Tahoe.

That person is represented by a well known Denver lawyer who has been negotiating with the Denver District Attorney's office, asking for immunity for his client in exchange for testimony against others in the suspected SUV. (Maass first reported that information Sunday night.)

Those negotiations recently broke-off, but the talks may provide a hint of how investigators feel about the man's testimony.

"Obviously, if this has gone on, they want this testimony badly," Cherner said.

Police and the DA's office said they would not publicly comment on the latest developments in the Williams' investigation.

CBS4 has decided not to identify the second possible suspect in the case, or his attorney, at the request of authorities who fear naming the people could jeopardize the possible suspect's safety and the investigation.
