— Family members of a man who was stabbed in his home April 3 say he died Wednesday evening. Crystal Mangum, the Durham woman who falsely accused three Duke University lacrosse players of rape in 2006, has been charged with assaulting him.

Durham police confirmed Thursday morning that Reginald Daye, 46, had died.

"The case remains under investigation, and we do anticipate upgrading the charges. However, no new charges have been filed at this time," police spokeswoman Kammie Michael said in an e-mail to WRAL News.

Police said Mangum, 32, stabbed Daye in the torso with a kitchen knife during a dispute at 3507 Century Oaks Drive early on April 3.

Daye was taken to Duke University Hospital, and Mangum was arrested in a nearby apartment.

A man who said he was Daye's nephew called 911 to report the stabbing, saying it occurred while Daye and his girlfriend were arguing about rent money. The caller said police came to the apartment complex earlier while the couple argued, but the stabbing occurred after the officers left.

When asked for a description of the girlfriend, the caller said, "It's Crystal Mangum. THE Crystal Mangum."

He then added, "I told him she was trouble from the beginning."

Mangum was charged with assault with a deadly weapon with intent to kill inflicting serious injury and was being held in the Durham County jail on a $300,000 bond.

In March 2006, Mangum claimed three white players on the Duke lacrosse team trapped her inside a bathroom at 610 N. Buchanan Blvd., where she was performing as a stripper at a team party, and raped and sexually assaulted her.

Her story about the incident was so inconsistent that state officials later declared the players innocent, saying there was no credible evidence against them.

Former Durham County District Attorney Mike Nifong was later disbarred for withholding DNA evidence from defense attorneys in the case.

The three lacrosse players and some of their former teammates are suing Nifong and a police investigator, claiming their rights were violated during the case.

In February 2010, police arrested Mangum after an altercation between her and a different boyfriend. In that incident, she was accused of assaulting the man in front of her children and setting some of his clothes on fire.

She was later convicted of child abuse, injury to personal property and resisting a public officer in the case, but prosecutors dismissed an arson charge after a jury couldn't reach a verdict.
