DENVER (AP) — The trial of a man accused of killing Denver Broncos cornerback Darrent Williams enters its third day of testimony with two witnesses getting another chance to testify after being jailed for refusing to do so.

Authorities say the two witnesses were in the same vehicle as Willie Clark when he allegedly fired the fatal shots into a limousine Williams was in, killing him almost instantly on New Year's Day 2007.

The people who refused to testify Wednesday in Denver District Court will be given a chance every day of the trial to change their minds. They'll be sent back to jail if they continue to refuse to testify.

Clark faces charges of first-degree murder, 16 counts of attempted murder and other charges. He says he is innocent.
