On January 1, 2007, Williams was shot during a drive-by shooting, at approximately 2:10 A.M. Williams and two other passengers were shot when another vehicle pulled beside his rented Hummer H2 limousine in downtown Denver, Colorado. The shooting occurred near 11th Ave. and Speer Blvd. It happened less than 12 hours after the Broncos played their final game of the 2006 season against the San Francisco 49ers in Denver.
Williams had been attending a New Year's Eve party and birthday party held for and by Denver Nuggets player Kenyon Martin at the nightclub, "The Shelter." The Denver Police Department reported that the shooting was preceded by some type of altercation or argument at the nightclub between Crips gang members and other unknown patrons. A police spokesman said, "There was some confrontation between a group of people in the vehicle and a group at the nightclub." Williams was not involved in the altercation.
According to the county coroner's office, Williams sustained a single gunshot wound to the neck, killing him instantly, . After Williams was shot, he fell in the lap of Broncos teammate, Javon Walker. He was pronounced dead around 2:30 a.m. The two other passengers injured in the shooting, Brandon Flowers and Nicole Reindl, were both released from the hospital the day after the shooting.
Denver police impounded a vehicle in connection with the shooting. [i][b]The suspected vehicle was registered to Brian Hicks, a 28-year-old Crips gang member, who was already incarcerated awaiting trial for attempted murder and drug charges. Other associates of Hicks were questioned as potential material witnesses to the Williams shooting. Rumors persist that it was a gang-related event; however, there hasn't been any concrete evidence to suggest that. Williams' family and teammates also say that the scenario was highly unlikely.
Williams was survived by his seven-year-old son, four-year-old daughter and 24-year-old girlfriend, all of whom live in Fort Worth, Texas. A memorial fund was set up in their name. Denver Nuggets stars, Carmelo Anthony and Kenyon Martin, who were with Williams at the nightclub the evening of the shooting, planned to honor their friend by possibly setting up a college fund for Williams' children. A fan-constructed memorial was formed on the southern wall of the fountain in front of Invesco Field at Mile High. Javon Walker decided to wear his hair in a "fro-hawk," in honor of Williams, who wore his hair in a similar way as a trademark.
On May 29, 2008, the Darrent Williams Memorial Teen Center was opened in Denver.
On May 30, 2008, the Rocky Mountain News published a story claiming that it had obtained a signed confession letter by Crips gang member Willie D. Clark, in which he admitted to firing the shots that killed Williams.
