While executing a search warrant, cops found two dark-colored masks inside suspect Michael Boatwright’s grandma’s car — matching the description of the masks allegedly bought by another suspect, Dedrick Williams, before the slaying, TMZ reported.
They also turned up .22-caliber ammunition — the same brand name and type of the casings found at the murder scene.
An AR-15-type assault weapon was also found in the trunk, on top of other soft gun cases, the gossip site reported.
Cops also searched Boatwright’s cellphone — turning up searches of the rapper’s name and “accessory to murder” just days after the fatal shooting.
Williams was the first suspect arrested in the case and Boatwright the second.
Robert Allen was the third to be taken into custody, and Trayvon Newsome was just arrested this week.
Williams was arrested June 20 on murder charges and Boatwright was arrested on July 5 on unrelated drug charges — and later hit with murder charges as well.
Allen, who was busted on July 26, faces first-degree murder, robbery and drug possession charges, according to ABC 10.
Newsome, nabbed on Tuesday, faces charges of first-degree murder and robbery with a deadly weapon.
The rapper was gunned down by two masked gunman outside RIVA Motorsports in Deerfield, Fla., on June 18.
