Derrick Parker, the former NYPD detective renowned as the "Hip-Hop Cop" for his role in the department's rap intelligence unit during the 1990s, has died at the age of 65. His brother, Ralph Parker, confirmed his death to Fox News Digital on Monday, stating that Parker died unexpectedly on July 24 at a Nassau County hospital. A funeral service is scheduled for Thursday at the J Foster Phillips Funeral Home in Jamaica, New York.

Parker led the NYPD's rap intelligence unit during a period when the city's hip-hop scene experienced explosive growth in popularity. His responsibilities included monitoring high-profile artists and their associates. He shared his strategies for reducing violence within the music industry with other cities, including Miami and Atlanta. His career in law enforcement spanned over two decades, during which he also served as a homicide and cold case detective and collaborated with federal agencies such as the U.S. Marshals, ATF, DEA, and FBI.

"You have to watch and see who’s coming to your city. Who’s there and who’s what," Parker said in a 2024 interview with Fox News Digital. "We can’t track everybody, but when certain people come to the city, you should know who, especially certain people that are on your radar. That’s the way I look at it."

A significant part of his work involved coordinating with law enforcement and nightclub management to anticipate the movements of individuals and groups to prevent potential conflicts between rival factions. Parker played a part in the 1999 investigation into a shooting at Club New York, an incident for which music mogul Sean "Diddy" Combs was charged but later acquitted. Pop star Jennifer Lopez was also briefly detained and released in connection with the event.

Parker's approach to policing the hip-hop community was not to aggressively target its stars. He stated in an interview, "I was the law, so he was always friendly. I’m never hard on these guys. They know what they get into. They know what trouble they have."

His experiences were documented in his book, "Notorious C.O.P.: The Inside Story of the Tupac, Biggie and Jam Master Jay Investigations from the NYPD’s First ‘Hip-Hop Cop.'" The book detailed his involvement in investigations surrounding the murders of Tupac Shakur, Christopher Wallace (The Notorious B.I.G.), and Jam Master Jay, whose real name was Jason Mizell. Decades after Mizell's death, Parker testified during the trial of his killers.

Following his retirement from the NYPD in 2002, Parker transitioned to roles in security for large events and executive protection, applying his expertise in conflict prevention by monitoring who was present at various venues. He also became a frequent media commentator on high-profile cases involving figures and locations from his NYPD career, including Combs' recent sex-trafficking trial and even celebrity events. Parker had expressed his intention to write a follow-up book.

In the days leading up to his death, Parker was closely following the Las Vegas murder case against Duane "Keffe D" Davis, who is charged in connection with Tupac Shakur’s 1996 murder. Jury selection for that case began on Monday.
