The Wizarding World of Harry Potter staff and guests gathered Monday for a moving tribute to an Orlando shooting victim who worked at the Universal theme park.

Taking a page from the Harry Potter films, park workers and attendees raised their wands in memory of 22-year-old Luis Velma, who was killed in last weekend’s mass shooting at a gay nightclub in Orlando.

“Tonight, we raise our wands to one of the greatest and best Gryffindors the world has ever known,” one of Velma’s friends says in a video of the event, posted to YouTube. “Tonight, we raise our wands to Luis Velma. He was brave, and he was one of the kindest souls you will ever meet in your life.”

Harry Potter author J.K. Rowling remembered Velma on her Twitter account. “Luis Velma worked on the Harry Potter ride at Universal. He was 22 years old. I can’t stop crying. #Orlando” she wrote.

Sunday’s shooting at the Pulse nightclub left 50 people dead, including the gunman, and dozens injured in the largest mass shooting in U.S. history.
