Mine

A man in a black shirt and cap holds a firearm while facing another man in a white shirt and backpack in a room with tables and chairs, the scene repeating in a loop. The video then cuts to a still photo of a smiling young man in a grey shirt sitting in a natural setting, followed by a clip of a man with long hair and sunglasses smoking a cigarette in front of a snowy tree, which also loops. The final frame is a black and white image of the man with sunglasses with the name "KLEBOLD" above him.
