That was fast!

The man believed to have gunned down XXXTentacion outside a motorcycle dealership was arrested on Wednesday evening in South Florida and booked for first degree murder.

Suspect Dedrick D. Williams, 22, has a lengthy rap sheet, with arrests for grand theft auto, cocaine possession, weapons possession, domestic violence, and aggravated assault with a firearm. He also once held a gun to his girlfriend's head during an argument! All in all, the dude has over 11 felonies, and it sounds like he's about to get his biggest one yet.

The late Soundcloud star's family learned of the arrest late Wednesday evening.

TMZ reports there are arrest warrants out for two other individuals that authorities believe were involved in the crime, but they've yet to be taken into custody or identified.

Now if they could only solve who killed Tupac!
