XXXTentacion's Accused Killers Found Guilty of Murder

The 3 men accused of killing XXXTentaction have just been found guilty of murder in the 2018 shooting.

The verdicts came in Monday for Michael Boatwright, Trayvon Newsome, and Dedrick Williams. The decisions follow the jury's deliberations, which started March 8.

As we reported, 20-year-old XXX was at a South Florida motorcycle dealership almost 5 years ago when prosecutors say he became the victim of a robbery -- getting shot while in his vehicle. They say the men ran off with $50K in cash and a Louis Vuitton bag.

The 3 were charged with first-degree murder with a firearm and armed robbery ... and in closing arguments last month, defense attorney Joseph Kimok claimed evidence clears all 3 men from the crime -- saying the DNA found on the rapper's body and necklace didn't belong to them.

You'll recall, a 4th man named Robert Allen was also arrested in connection to the killing ... but he pled guilty last year to second-degree murder and agreed to testify against the other 3 suspects, adding he was hesitant about the robbery and even asked the others to ditch the idea in the moment.

In a discovery and bail hearing for Allen back in 2018, surveillance video from the dealership was shown -- which appeared to show the entire thing going down in real time.
