A music executive who authorities say is a leader of a notorious Los Angeles street gang appeared in court Tuesday to face a wide range of charges, including extortion, racketeering, and conspiracy.

Eugene “Big U” Henley, accused leader of the Rollin’ 60s Neighborhood Crips, pleaded not guilty to the charges Tuesday morning. His trial is set to begin on May 20, a spokesperson for U.S. Attorney’s Office said.

Henley, 58, turned himself into authorities last month on charges of fraud, robbery, extortion, human trafficking, embezzlement and leading a “mafia-like” criminal enterprise that was responsible for the murder of Rayshawn Williams, an aspiring rapper who had recorded a diss track about him.

Federal investigators allege Henley, who billed himself as both an “OG” — original gangster — and an anti-gang activist, shot and killed Williams, then “dragged the victim’s body off Interstate 15 in Las Vegas and left it in a ditch” in January 2021.

He’s also accused of using his stature as a prominent figure in the famed street gang to extort wealthy individuals, like celebrities and professional athletes, requiring them to “check in” with him when visiting the city and coercing them to pay for protection.
