As Las Vegas police attempt Wednesday to sway the district attorney that it has a stronger case against Adam "Pacman" Jones, the suspended NFL player's agent has confirmed that Jones has provided DNA samples that twice have tested negative in connection with a fight inside a Vegas strip club. "Yes, that's true," said Michael Huyghue, Jones' agent, of the DNA results. Sources say that Jones voluntarily submitted his DNA to Las Vegas police "more than a month ago" to determine whether Jones could be linked to DNA that was gathered in connection with the fight inside the club and a shooting outside that left a strip club bouncer paralyzed. Jones gave saliva samples to Las Vegas police, who traveled to Atlanta, Jones' hometown, to collect it. Jones' DNA sample twice has returned negative results for what apparently included an allegation of a bite during the fight, Huyghue said. The incident occurred during NBA All-Star weekend in February. "I guess they were hoping it was him," he said.
