Joseph Cheshire, an attorney representing a team captain not charged in the case, told reporters that semen found on a vaginal swab taken from the accuser was from a "single male source," but it was not a match for any of the team players, all of whom submitted DNA for comparison.
"In other words, it appears this woman had sex with a male," said Cheshire. "It also appears with certainty it wasn't a Duke lacrosse player."
Cheshire also said the DNA report included the name of the man whose DNA was found inside the accuser. The man "is known to the Durham police department" he said, but declined to identify him.
"There is no indication that this man should have his name dragged through the mud," he said.
Duke Lacrosse DNA: Mystery Man Revealed
ABC News' Law and Justice Unit has learned that the unnamed source of the DNA is the alleged victim's "boyfriend," according to the victim's mother.
The attorney also said that genetic material from several people was found on a plastic fingernail recovered from a bathroom trash can at the party. He said some of that material had the "same characteristics" to some of the players, but not the two who have been charged with rape, kidnapping and sexual assault.
Cheshire told a news conference the fact that the players voluntarily turned over the fingernail indicates they had nothing to hide.
"Is that consistent with someone that knowledgeably and knowingly committed a rape?" Cheshire said. "That they would leave fingernails that were ripped off a person in a violent struggle in their trash can after they're told there's an investigation and that police were going to come to their house, and when the police do, they give them the fingernails?"
