Robert Allen is expected to testify against his co-defendants at trial for the 2018 killing of Florida hip-hop artist XXXTentacion. Allen was part of what some have dubbed a “rob and kill” team that robbed and then killed the Florida MC.

XXXTentacion, whose real name was Jahseh Dwayne Ricardo Onfroy, was on a fast track to fame. After his song “Look at Me” climbed to No. 34 on the Billboard Hot 100 in 2015, he caught the attention of the music industry. “Look at Me” connected with a broad fan base as it documented XXXTentacion’s mental health struggles. In March 2018, XXXTentacion’s sophomore album “?” debuted at No. 1 on the Billboard 200. A few months later, he reportedly secured a $6 million record deal with a Capitol Music Group subsidiary, NBC reported.

XXXTentacion, 20, had just left motorcycle dealership RIVA Motorsports in Deerfield Beach, north of Miami, around 4 p.m. on June 18, 2018, when he was approached by two armed men. At least one of them opened fire and shot the artist before fleeing in a dark-colored SUV. According to investigators, the robbers fled with a Louis Vuitton bag filled with $50,000 in cash.

At the time of his death, XXXTentacion was said to have a net worth of $5 million.

Allen, one of the co-defendants in the murder of XXXTentacion, has accepted a plea deal and will be testifying for the state. He pleaded guilty and has agreed to testify against his co-defendants Michael Boatwright, Dedrick Williams, and Trayvon Newsome.

Street surveillance video captured images of Allen outside of the motorcycle dealership where XXXTentacion was shot and killed.

Allen was facing a possible life sentence.

“Robert Allen… entered a guilty plea,” Allen’s attorney Jim Lewis said. “He pled to a lesser included offense of second-degree murder and robbery with a firearm.”

Allen’s sentencing is scheduled for Feb. 23, 2023 CBS News reported.
