On Wednesday (June 27), friends, family and fans of XXXTentacion, who was shot and killed during an apparent robbery on June 18, attended an open-casket public viewing for the slain rapper. Among the guests at the event, which is currently taking place at Sunrise, Fla.'s BB&T Center (the Florida Panthers Stadium), were former members of the XXL Freshmen Class including Lil Uzi Vert, PnB Rock and Ugly God. Denzel Curry, Fat Nick, Kid Trunks, Ronny J and some of X's friends were also in attendance.

Other attendees include Rolling Loud co-founder, Tariq Cherif and John Cunningham, who executive-produced X's album. During his time at the event, Cunningham could be seen gathering people to help carry handicapped fans to the stage so they could see X in his casket.

Local Florida news outlets report that the memorial, which is taking place today until 6 p.m. EST, is supposedly going to be attended by as many as 20,000 people. According to USA Today, at least 1,000 people had arrived to attend the memorial by 12 p.m. EST. Even with his legion of loyal fans, many of whom are wearing X's signature Revenge hoodies and XXXTentacion shirts, Uzi, PnB and Ugly God stood out.

Uzi, who's just pledged to start a foundation to help support X's family, stood at X's casket with his mother, Cleopatra Bernard, as they peered down at the rapper, who was wearing a denim jacket. His hair was as blue as it was the day he passed. X's platinum-selling song "Changes," which features PnB, played as the two stood at the casket of the late rapper. PnB, who posted an emotional behind-the-scenes video of himself and X recording the song in tribute days after his death, watched Uzi and XXXTentacion's mother as the song played. Ugly God could be seen sobbing.

For an event of such size, X's memorial is remarkably well-organized and attendees are said to be following directions given to them. Fans could be seen making X signs with their arms or crying as they walk on and off the stage on which the rapper's casket rests. Some knelt before the casket and said prayers before stepping off the stage. The late rapper's music played on repeat, as did intermittent messages from X.

At another point of the viewing, "Look At Me!," which was X's breakout single released in 2015, began playing over the loud speakers and the crowd began chanting.

The set up for the stage includes a dozen bouquets of silver leaves and black roses. Two large screens hang on either side of the curtain hanging behind the casket. The stadium's scoreboard played an X tribute video, which was created by Justin Staple, Quinton Dominguez, and Tyler Benz.

In the video, archival footage of X in concert or servicing his community can be seen, while his tracks like his song, "Alone, Part 3," play in the background.

XXXTentacion passed just over a week ago, but the Broward Sheriff's Office has already made a key arrest. Last Wednesday (June 20), they arrested Dedrick Williams, who they believe may have been the getaway driver for those who shot and killed X. Williams has pled not guilty to first-degree murder. The police are searching for two more suspects who they believe actually shot the 20-year-old rapper. Authorities named 22-year-old Robert Allen as a person of interest earlier today (June 27).
