Shocking footage of Charlie Kirk's killer: Here's how he got away VIDEO

Utah's governor said they are releasing this information to "get the public's help" in finding "an evil human being."

The video opens with a shot of the building from which the shot that killed Kirk was fired. The video shows a man dressed in black running across the roof to the corner of the building, where he drops over the edge and onto the grass below, before walking to a nearby road and disappearing into the woods.

Authorities say the suspect was wearing sunglasses, Converse sneakers and a "distinctive" black T-shirt with an American flag and eagle on it.

"We are only asking for the cooperation of the public. We receive various reports from the public, they give us clues and enable us to continue the investigation," said a senior official of the investigation.
