A 22-year-old was arrested around 7pm local time on Wednesday.
Dedrick Devonshay Williams has been charged with first-degree murder without premeditation after XXXTentacion, 20, was shot dead on Monday afternoon.
The rapper, whose real name is Jahseh Onfroy, was attacked by two hooded assailants after leaving a motorcycle dealership in Deerfield Beach, north of Miami.
The rapper, whose stage name is pronounced “Ex Ex Ex ten-ta-see-YAWN,” was shot while in his sports car.
The fatal shooting came just months after the victim was released from house arrest in relation to a charge of domestic violence against his pregnant girlfriend.
He had been awaiting trial to answer to the allegations, which stemmed from an incident last October.
Williams is being held without bond in Broward County Jail.
