One week to the day after the YouTube star and The Voice contestant was tragically killed by an obsessed fan in an Orlando, Florida night club following a performance, the family of Christina Grimmie posted a poignant tribute to the late singer on her Youtube page. Set against the singer’s performance of Jason Mraz’s “I Won’t Give Up,” the tribute is a montage of Christina’s video messages to her devoted YouTube audience and offers them an emotional coda to her short life. “Christina Grimmie was taken from all of us far too soon,” the video’s caption reads, “but the impact she had on this world in the short 22 years of her life will carry on forever.”

Befitting Grimmie’s social media success during her career, within 24 hours of being posted the tribute has garnered over one million views on Youtube. That outpouring of grief is likely to continue later this month at the 7th annual VidCon convention in Anaheim, California, where creators, entertainment industry reps and fans converge to celebrate online content and its creators. In the wake of Grimmie’s death, VidCon has enacted dramatic changes to security procedures to safeguard attending YouTube personalities, among them a fenced off perimeter, beefed up undercover security, and mandatory bag checks and metal detectors for meet and greet events.

Grimmie’s murder came one day before the horrific Orlando Shootings, when 50 people were killed and 53 injured by a gunman who pledged allegiance to ISIS, but who authorities investigating the tragedy have since revealed bears few similarities to radicalized terrorists. (Among other things, he was later found to have been a patron of the club he destroyed and a user of gay dating apps who investigators are saying has a profile more similar to a “typical mass shooter” according to news reports published this weekend.)
