FORT LAUDERDALE, Florida (AP) — More than four years after gunmen killed emerging rap star XXXTentacion during a robbery outside a South Florida motorcycle shop, three suspects are now scheduled to go on trial.

Shooting suspect Michael Boatwright, 28, and his accused accomplices, Dedrick Williams, 26, and Trayvon Newsome, 24, could all receive life sentences if convicted of first-degree murder. They are also charged with armed robbery. They have pleaded not guilty.

A fourth man, Robert Allen, 26, pleaded guilty to second-degree murder last year and is expected to testify against the other three. Jury selection is set to begin January 18 and is expected to last three weeks. The trial is expected to last into March.

In pretrial hearings, the defendants’ attorneys have suggested there were others who had financial and personal motives for killing the singer, including members of his family and other rappers.

“It’s been over four long years in the making. We are excited to take this first step to bringing Dedrick home,” said Mauricio Padilla, Williams’ attorney.

The attorneys for Boatwright and Newsome did not respond to emails seeking comment. The COVID-19 pandemic and legal wrangling delayed the start of the trial.

Circuit Judge Michael Usan rejected last week an attempt by Boatwright’s attorney, Joseph Kimok, to have him declared mentally incompetent to stand trial. He also rejected a motion by the defendants’ attorneys to try the three separately.

They argued that evidence presented against just one defendant would be prejudicial to the other two. They also argued that each defense attorney could try to establish his client’s innocence or mitigate his guilt by pointing fingers at the other two suspects — they argued that would unfairly prejudice the jury against the trio. Prosecutor Pascale Achille told Usan that any evidence presented would pertain to all three.

Usan ruled the defense attorneys’ arguments could apply in all trials where there are multiple defendants, but in this case they don’t outweigh the needs of “judicial economy” to not hold three trials if not absolutely required.

XXXTentacion, whose real name was Jahseh Onfroy, had just left Riva Motorsports in suburban Fort Lauderdale on June 18, 2018, with a friend when his BMW was blocked by an SUV that swerved in front. Two masked gunmen emerged, confronted XXXTentacion at the driver’s window and one shot him. They then grabbed a Louis Vuitton bag containing $50,000 cash the singer had just withdrawn from the bank, got back into the SUV and sped away.

XXXTentacion, 20, died at the hospital shortly after. He pronounced his name “Ex ex ex ten-ta-see-YAWN” and was a platinum-selling rising star who tackled issues including prejudice and depression in his songs. He also drew criticism over bad behavior and multiple arrests, including charges that he severely beat and abused his girlfriend.

Investigators say surveillance video from the store and other evidence links the three defendants and Allen to the killing.
