J.K. Rowling Mourns Orlando Victim Who Worked on 'Harry Potter' Ride

Late Saturday night/early Sunday morning, the U.S. experienced its largest mass shooting ever. The lone shooter, 29-year-old Omar Mateen, entered Pulse, an LGBT nightclub in Orlando, Fla. around 2 a.m., killing 50 and injuring at least 53 others. As time progresses we're learning more and more about the victims and the assailant. 

One of the many who lost their lives is Luis Vielma, a 22-year-old man who worked at Universal Studios' Harry Potter World. J.K. Rowling caught wind of this and sent the above tweet, featuring Vielma in his Gryffindor attire.
