Police arrested another suspect in connection with the death of rapper XXXTentacion Wednesday, according to a press release from the Broward County Sheriff's Office. Investigators allege that Michael Boatwright, 22, was “one of the two armed suspects who confronted Jahseh Onfroy, aka XXXTentacion, when he was killed in broad daylight on June 18,” in a murder that shocked the rap community. Boatwright was served Tuesday with an arrest warrant for first-degree murder while in jail for an unrelated drug charge; he was served an “additional charge of first-degree murder” Wednesday. Dedrick Devonshay Williams, 22, was also arrested last month. The report adds that detectives are still looking for the second gunman, and are also tracking down a man named Robert Allen, whom they consider a “person of interest” in the investigation.
