The man accused of orchestrating the mass shooting at a FedEx facility in Indianapolis was a "brony," a term used to refer to adult male followers of the girls' television show My Little Pony, Washington Examiner reports.
Brandon Scott Hole, allegedly murdered eight people before taking his own life.
While Hole's Facebook page has since been taken down. While it offered no clues on what motivated Hole's rampage, it did reveal that he was a fan of the Vancouver-produced television show.
"I hope that I can be with Applejack in the afterlife, my life has no meaning without her," Hole posted shortly before the shooting. Applejack is one of the main ponies on the show.
The brony fandom first began in the early 2010s as a joke, but has since developed into a genuine subculture of adult fans.
Hole, a former employee of the FedEx facility, was placed in a mental hospital after his mother reported that he may intend to commit "suicide by cop," a practice by which suicidal people provoke a police officer into taking their life when they feel unable or unwilling to do it themselves.
