On Friday, June 10, hours before she was set to take the stage at “The Plaza Live”, singer Christina Grimmie encouraged fans via Twitter to come out to the show.

Following the show, the 22-year-old YouTube star and Season 6 contestant on NBC’s “The Voice” was meeting fans in the venue’s lobby at a meet-and-greet that turned into a nightmare.

Kevin Loibl, 27, walked up to Grimmie while she was signing autographs and shot her. Grimmie’s brother tackled Loibl, but he was able to break free, back himself up against a wall, and shoot himself.

Grimmie later died at Orlando Regional Medical Center.

Police later described Loibl as an “infatuated fan” who they said traveled from St. Petersburg to Orlando carrying two handguns and a hunting knife intending to kill Grimmie. Though security at The Plaza Live was performing bag checks that night, the venue had no metal detectors, and there were no extra off-duty officers working the event.

Four days later, when The Plaza Live re-opened, a memorial for Grimmie stood outside the venue. The venue also paid tribute to the singer, as well as the victims of the Pulse nightclub shooting that occurred less than 24 hours after Grimmie’s death, on their main billboard.

Grimmie was buried in her home state of New Jersey on June 16. Her death prompted calls from the entertainment industry for increased security at performing venues.

On June 23, Billboard magazine published “An Open Letter to Congress: Stop Gun Violence Now.” The letter renewed the call for background checks for every gun purchase and an outright ban on sales to suspected terrorists.  The letter was signed by over 200 music industry stars.
