XXXTentacion was fatally murdered last month.
XXXTentacion was shot and killed outside a motorcycle dealership on June 18 in Deerfield Beach, Florida. The suspects fled after stealing a branded bag that authorities said contained $50,000 in cash.
His girlfriend also spoke to the police, saying he'd told her that Boatwright and Newsome carried out the robbery and were responsible for the death. Since then, police officials were searching for Newsome and Allen.
Trayvon Newsome and Robert Allen are wanted by police
Detectives have already arrested two of the men. Two gunmen - believed to be Boatwright and Newsom - jumped out of the vehicle and shot the rapper and robbed him, the Broward County Sheriff's Office said.
Police were initially looking for two men in connection with the shooting, a sheriff's spokesperson said at the time. Not long after exiting the shop, he returned to his auto which was parked near the store.
Surveillance video of the scene at Riva's shows Allen and Williams together shortly before the robbery, the warrant states. A store clerk is also on record as having sold him a black mask. Fort Lauderdale police identified Newsome as the driver.
Authorities seized several items from Williams' home, including a live.22-caliber round that matched casings recovered from the crime scene, along with items of clothing with tags still on them, and a receipt for nearly $800 of clothes bought at a Fort Lauderdale store the day after the killing, the affidavit said. On July 10, detectives served him with an arrest warrant for first-degree murder while at the Broward Sheriff's Office Main Jail. Prior to going to the motorcycle shop, it was revealed that the rapper took out a large sum of money at the bank. "He had released two full-length albums during his brief career - "17" in 2017 (via Empire) and "?" in 2018 (via Caroline/Universal Music Group) - as well as a number of mixtapes and one-off tracks.
