Almost immediately, the man who had struck Rittenhouse with his skateboard, Anthony Huber, hit him with the skateboard again, and Rittenhouse fired a single round, killing Huber. A third man, Gaige Grosskreutz, saw this and approached Rittenhouse with his hands up. However, when Rittenhouse looked down for a split second, Grosskreutz pulled out a handgun and pointed it at Rittenhouse's head. Rittenhouse fired a single shot, striking Grosskreutz in the arm.
Jump Kick Man, whose attack on Rittenhouse (and Rittenhouse's subsequent response) arguably led to both Huber's and Grosskreutz's actions (and Rittenhouse's response to them), has never been identified--until now.
