J.K. Rowling remembered one of the victims of the mass shooting in Orlando, Florida that took place in gay nightclub Pulse early Sunday morning and left more than 50 dead.

“Luis Vielma worked on the Harry Potter ride at Universal,” she tweeted with a photo of Vielma. “He was 22 years old. I can’t stop crying.” According to the Orlando Sentinel, he worked on the Harry Potter and the Forbidden Journey ride.

The Harry Potter scribe also retweeted memories of Vielma from people who remembered meeting him at Universal. “He was the guy in the breakroom you liked four seconds after walking in,” Melissa A. Gibbo ‏wrote. “He was SO nice to my son, such a lovely guy,” Sarah Moore said.

Vielma is just one of the 50 victims of the Orlando shooting, which President Barack Obama declared “the most deadly shooting in American history.”
