Dedrick D. Williams was arrested for the murder of XXXTentacion last week.

He probably wasn't the shooter. Police believe he was behind the wheel of the SUV which blocked X's BMW right before his accomplices opened fire.

There are two more warrants out, with possibly more to come, and Federal Marshals have now joined the Broward County Sheriff's Dept. in tracking down X's killers.

As for Williams, he pled not guilty in Broward County court yesterday. Police have said that they have him on surveillance video in Riva Motorsports in Deerfield Beach right before X was ambushed and killed. Eyewitnesses also tie him to the murder.

A public memorial with an open-casket viewing will be held for XXXTentacion from 12 to 6 p.m. today [June 27] at the BB&T Center in Sunrise, Florida.
