The investigation into the murder of XXXTentacion continues to unfold and now, police have identified a second person of interest who they believe may have been connected to the June 18 killing.

Broward Sheriff's office confirmed to XXL today (June 27) that police are now searching for 22-year-old Robert Allen. Authorities say Allen could be seen in the surveillance video from RIVA Motorsports, where XXXTentacion was gunned down.

While it's uncertain how cops believe Allen is tied to the murder, police previously issued two more warrants after arresting and charging Dedrick D. Williams with first-degree murder. According to the Florida Department of Corrections, Allen was already on felony probation until 2021 for 21 charges of fraudulent use of personal identification.

According to the arrest warrant for Williams, police believe he was behind the wheel of the SUV that was used to block XXXTentacion from leaving. After reportedly blocking X's vehicle, two more men who were inside the SUV robbed the rapper at gunpoint. Warrants for the two other suspects have reportedly been issued, although no further arrests have been made.

Williams has since pleaded not guilty to his charge of first-degree murder.

U.S. Marshals have also joined the investigation and are assisting local authorities in the hunt for the other suspects. According to agency spokesman Dave Oney, federal investigators are currently in Florida helping Broward County officers.
