The search continues for the remaining two suspects in XXXTENTACION‘s shooting death.

And according to TMZ, federal agents are part of the effort to find the suspects — an effort that has now expanded outside of Broward County.

The U.S. Marshals and Broward County Sheriff’s Department are working together to find two more people accused of being involved in the shooting, following last week’s arrest of Dedrick D. Williams.

Williams was arrested on June 20, just two days after X was killed. His charges include first-degree murder, probation violation for theft of a motor vehicle, and driving without a valid license.

U.S. Marshals reportedly played a role in tracking down and arresting Williams.

Since his arrest, Williams has been arraigned and, according to his lawyer, the 22-year-old has pleaded not guilty to murder.

XXXTENTACION was shot and killed in Florida on June 18 while outside of a motorcycle shop he had just visited.

A memorial will be held for him at BB&T Center in Florida on Wednesday (June 27).
