One of four suspects in the shooting death of rapper XXXTentacion was being held in a south Georgia jail Thursday following his arrest at his sister’s home.

Robert Allen, of Fort Lauderdale, is accused of killing the rapper on June 18 and last week was indicted by a Broward County, Fla., grand jury. Allen was found more than 500 miles away at a home in Dodge County, about an hour southeast of Macon, and arrested without incident Wednesday, according to media reports.

The 20-year-old rapper, whose real name is Jahseh Onfroy, was shot and killed June 18 in an apparent robbery attempt as he was leaving RIVA Motorsports in Deerfield Beach, Fla., according to Broward County sheriff’s deputies. A week after his death, the rapper earned a posthumous No. 1 hit with his song “SAD!” on the Billboard Hot 100.

Two other suspects have been jailed in connection with Onfroy’s death. Michael Boatwright, 22 and Dedrick Williams, 22, are jailed in Florida on charges of murder and robbery. Boatwright is the alleged shooter, according to the indictment.

But Allen remained on the run until Wednesday.

Deputy U.S. Marshal John Edgar told the Macon Telegraph that Allen was arrested after authorities learned that he might be staying with his sister in Eastman, Ga. Edgar said Allen's sister was cooperative when authorities asked about him.

"It was uneventful," Edgar told the Telegraph. "This is a good case."

Allen is expected to be returned to Broward County.

One other suspect, 20-year-old Trayvon Newsome, still remains at large.
