Trayvon Newsome, 20, has turned himself in after the arrests of Robert Allen, Michael Boatwright and Dedrick Devonshay Williams. Trayvon surrendered himself at his lawyer’s office.

All four men were indicted last month by a Broward County grand jury on first-degree murder and armed robbery charges. Trayvon is suspected to be the second shooter in the murder of XXXTentacion outside a motorcycle dealership in Deerfield Beach, Florida.

XXXTentacion, whose real name was Jahseh Onfroy, was gunned down in the front seat of his BMW after leaving the motorcycle dealership. The 20-year-old died just months after scoring a No. 1 album and his first top-10 single. He was also awaiting trial for alleged domestic abuse, for which he had pleaded not guilty.

Police said Newsome and Boatright are the men who confronted him and that Boatright allegedly fired the fatal shots. The rapper’s attorney mentioned in a statement that XXXTentacion had visited a bank shortly before the shooting, possibly to withdraw cash to buy a motorcycle.

According to court documents, the rapper was robbed of $50,000, all in hundred-dollar bills in bank wrappers, which he had tucked into a Louis Vuitton bag.
