Born May 24, 1960. Also known as The Shrapnel Bomber. Barrow is an electrical engineer. He is undergoing surgery to remove a tumor. In the pre-op interview, he tells Melissa McCall that he killed the kids he did because they had glowing eyes.
The tumor turns out to be filled with flies. Barrow escapes the hospital and goes straight for the school, where he patches himself up with a staple gun in Coach Finstock's office.
It turns out that he's after Kira. He follows her to the library, but Finstock unwittingly saves her. Barrow later finds Kira at her house. He knocks Scott out with a tire iron and brings Kira to a power substation. He takes a photo of her to prove that her eyes glow and then touches her with an electrical main. The substation explodes, and Barrow appears to die from electrocution.
