The identities of some of the 50 people who were killed in a nightclub shooting in Orlando on Sunday have been released by police, and among them is Luis Vielma, a 22-year-old who worked at the Harry Potter and the Forbidden Journey ride at the Universal Orlando theme park. "Potter" author J.K. Rowling has been paying tribute to the young man on her Twitter page, where she's been mourning Vielma and the other victims alongside friends, coworkers, and complete strangers.

Rowling posted a photo of Vielma, dressed in his Universal uniform -- which looks like the official Hogwarts uniform -- and sporting a tie in Gryffindor colors. "I can't stop crying," Rowling wrote.

The author also retweeted many messages from both those who knew Vielma well, including friends and coworkers, as well as theme park goers who remembered him from their visits to Universal. One fellow Universal employee tweeted at Rowling that another coworker, named Tony, was also injured in the shooting, and is currently in the ICU. "I'm praying Tony pulls through," Rowling responded. "My thoughts are with all of you."

Universal Orlando also released an official statement about Vielma's passing (which Rowling retweeted), saying, "We are deeply saddened over the loss of our Team Member. We are working to support his friends and colleagues here at Universal Orlando. Our thoughts and prayers are with Luis, his family, and all the victims of this tragedy."

"[Luis] was a true friend," coworker Olga Glomba told The Orlando Sentinel. "A funny, sweet, nerdy guy without a mean side. He just wanted to make people smile."

More information about the other victims of the shooting can be found through The Orlando Sentinel here.
