As noted on the blog Robot 6, a soldier in Virginia who was obsessed with the Joker stabbed a fellow soldier and was later killed in a shootout. The soldier, Army Spc. Christopher Lanum, was dressed in the Joker costume he wore on Halloween, which included a green vest and face-paint. He also had masks and pictures of the Joker in his apartment.
His girlfriend confirmed Lanum's obsession with the character of the Joker from the movie "The Dark Knight," and also noted that Lanum,
"...said everything the Joker did he did for a reason, like killing people, and that he agreed with the philosophy of doing things for a reason."
2009 has been a busy year for Joker-inspired attacks, with incidents in Belgium, Indiana, and Wisconsin.
