Rittenhouse has been arrested and charged with murder after he shot three people during the rioting in Kenosha, Wisconsin, on Tuesday night. Two died, and a third, Grosskreutz, has had surgery to repair a massive bullet wound to his bicep.

Grosskreutz was one of two men caught on video attacking Rittenhouse, who was apparently fleeing the scene of the first shooting. As gunshots rang out from an unknown source, Grosskreutz moved in on Rittenhouse, who at this point was lying on his back after shooting the second man. When Rittenhouse aimed his rifle at Grosskreutz, the man backed off. However, when Grosskreutz moved in again, this time apparently with a pistol drawn, Rittenhouse unloaded a round into his arm.

With the public divided over whether Rittenhouse acted in self-defense, a series of Facebook posts by Grosskreutz’ friend, Jacob Marshall, went viral on Thursday. In comments under a photo of Grosskreutz after surgery, Marshall described how Gaige had his gun drawn at the time of the shooting.
