Reginald Daye

In November 2013, she was found guilty of second-degree murder after she stabbed boyfriend Reginald Daye, who died 10 days after. She argued that she acted in self-defense, fearing that Daye would kill her. She was sentenced to 14 to 18 years in prison.

On November 22, 2013, she was convicted of second-degree murder by a jury of seven men and five women. Judge Paul Ridgeway sentenced her to serve a minimum of 14 years, 2 months and a maximum of 18 years in prison. According to the North Carolina Department of Public Safety, she is projected to be released from prison on February 27, 2026.

On May 1, 2012, Mangum's attorney withdrew, citing the release by Mangum of confidential information regarding her case to her supporters. On February 20, 2013, Mangum was released on bail until trial.

A version of the story of Daye's killing was featured in an episode of Wives with Knives, which aired December 12, 2012, during its first season on Investigation Discovery. Mangum appeared in the episode, having given a jailhouse interview to the show's producers in the summer of 2012. The interview focused mostly on the murder and not the Duke lacrosse case. Daye's murder was featured on an episode of Fatal Attraction, called "Toxic Romance", which aired on TV One on August 4, 2014 (Season 2 Episode 23). An episode of Snapped, which aired on October 7, 2018, titled "Crystal Mangum", detailed her story and Daye's murder.

After the verdict, Judge Abe Jones sentenced Mangum to 88 days in jail, which she had already served, and left the custody decision in the hands of social services. Durham Assistant District Attorney Mark McCullough announced on January 21, 2011, that he would not retry Mangum on arson charges.

Mangum was arrested on April 3, 2011, following accusations that she repeatedly stabbed and seriously injured a boyfriend, Reginald Daye. She was charged with assault with a deadly weapon with intent to kill or inflicting serious bodily injury, a class C felony in North Carolina. Ten days later, Daye died in the hospital, and Mangum was indicted on a murder charge. Mangum was held in jail under a $300,000 secured bail bond, which was set prior to her boyfriend's death. On November 1, 2011, Mangum was deemed competent to stand trial for murder.

In February 2010, she was arrested on charges of attempted murder of her live-in partner, Milton Walker. She was eventually convicted of contributing to the delinquency of a juvenile, injury to personal property and resisting a public officer.

Just before midnight on February 17, 2010, Durham police were called to Mangum's residence by her nine-year-old daughter. When they arrived, they said they found Mangum and her live-in partner, Milton Walker, fighting. She reportedly set fire to some of his clothing in a bathtub in their presence. The building suffered heavy smoke damage. They arrested Mangum on charges of attempted murder, first-degree arson, assault and battery, identity theft, communicating threats, damage to property, resisting an officer, and misdemeanor child abuse.

Mangum was ordered to remain in jail on $1 million bond. Her bond was lowered to $100,000 in May, and she was released from jail to live in a friend's house. She was required to wear an electronic monitoring device. On July 12, 2010, she was released from house arrest and required to move in with her mother. She was allowed to visit her three children but only under supervision of social services. Mangum was arrested again on August 25, 2010, and held on $150,000 bond for failure to comply with the restrictions on her child visitation order.

On December 17, 2010, Mangum was convicted of contributing to the delinquency of a juvenile, injury to personal property and resisting a public officer. The jury deadlocked 9–3 for not guilty on the felony arson charge but was unable to reach a decision on it.

In 2008, Mangum published a memoir, The Last Dance for Grace: the Crystal Mangum Story, written with Vincent Clark. The book gives her version of events. She continued to insist that she was assaulted at the party and says that the dropping of the case was politically motivated. The book also outlines her earlier life, reasserting her claim that she was raped at the age of 14.

In March 2006, she was hired as a stripper at a party organized by members of the Duke University men's lacrosse team. After arriving in an intoxicated state, having earlier consumed alcohol and cyclobenzaprine, to perform with another stripper at a house rented by three of the team captains, she became involved in an argument with the occupants of the residence and subsequently left. She then became involved in an altercation with her fellow stripper that necessitated police assistance. The officer who arrived on scene took her to a local drug and mental health center, where she was in the process of being involuntarily committed when, after being asked a leading question, she made an allegation that she had been raped at the party. District Attorney Mike Nifong, who was up for re-election, pursued the case despite questions about the credibility of Mangum, and conspired with a DNA lab director to withhold exculpatory evidence that would have cleared the lacrosse players of the rape accusations. It took almost a year for the state's attorney general's office to dismiss the charges and declare that the players were innocent of the charges laid against them by Nifong.

In 2004, she gained an associate degree in police psychology and then enrolled full-time at North Carolina Central University to study the subject.

By 2002, Mangum had returned to Durham and was working as an exotic dancer. In 2002, she was arrested on 10 charges after stealing the taxicab of a customer to whom she had given a lap dance. This prompted a police pursuit at speeds of up to 70 miles per hour, occasionally in the wrong lane. After being stopped, she nearly ran over a police officer, succeeding only in hitting his patrol vehicle. She was found to have a blood alcohol content of over twice the legal limit. Ultimately, she pleaded guilty on four counts: assault on a government official, larceny, speeding to elude arrest, and driving while impaired, serving three weekends in jail, paying $4,200 in restitution and fees, and being given two years' probation.

Mangum was born and grew up in Durham, North Carolina, the daughter of Travis Mangum, a truck driver, and his wife Mary. She was the youngest of three children. She attended Hillside High School, graduating in 1996.

In 1996 she filed a police report alleging that three years earlier, when she was 14, she had been kidnapped by three assailants, driven to Creedmoor, North Carolina, and raped. One of those she accused was her boyfriend, who was 21 at the time, which would be statutory rape. She subsequently backed away from the charges, a move relatives claimed was motivated by fear for her life. Mangum's father said he did not believe she was raped or injured, though her mother believed such an incident could have occurred—but not in 1993. She thinks it is more likely to have happened when Crystal was 17 or 18 years old, shortly before she made the police report. Mangum's ex-husband, Kenneth Nathanial McNeill, believed the incident occurred as she said it did.

After graduation from high school in 1996, she joined the US Navy. She trained to operate radios and navigation technology. While serving in the Navy, she married McNeill. Her marriage quickly broke down. She reported to police that her husband had threatened to kill her, but the charge was dismissed when she failed to appear in court. She served for less than two years in the Navy before being discharged after becoming pregnant by a fellow sailor, with whom she went on to have another child.

Crystal Gail Mangum (born July 18, 1978) is a woman from Durham, North Carolina, who is best known for making false allegations of rape against lacrosse players in the 2006 Duke lacrosse case. The fact that Mangum was a black woman working in the sex industry, while the accused were all white men, created extensive media interest and academic debate about race, class, gender and the politicization of the justice system.
