"So… this happened," Vielma's friend Tim McKenny posted to his Facebook on Friday, along with photos of Rowling's message. "To Louis, who died for love. You will never be forgotten," Rowling's note read.
The British writer's kind note follows the heartfelt message she shared via Twitter on Monday.
"Luis Vielma worked on the Harry Potter ride at Universal. He was 22 years old," she tweeted. "I can't stop crying."
