A brief but haunting Snapchat video shows the last moments of nine people gathered for a Bible study at Emanuel African Methodist Church in Charleston before they were massacred by alleged shooter Dylann Roof. You can see Roof in the frame.

The Snapchat was filmed by 26-year-old Tywanza Sanders and obtained by Mashable. It shows the group sitting around a table with books and paper spread in front of them, talking. Over the shoulder of one participant and seated at the far end of the table, you can see a white, a sandy-haired person who Sanders' friends told Mashable was Roof.

Sanders, known as "Wanza" by his friends, died heroically trying to shield his 87-year-old aunt, Susie Jackson, from Roof's bullets, People Magazine reports. He graduated last year with a degree in business administration and wanted to open a barber shop, and was considering graduate school. Photos of him posted to Twitter by grieving friends show a young man with a broad, friendly smile.

Also killed in the terrorist attack were South Carolina State Sen. and church Reverend Clementa Pinckney, 41, Cynthia Hurd, 54, Rev. Sharonda Coleman-Singleton, 45, Ethel Lance, 70, Depayne Middleton Doctor, 49, Rev. Daniel Simmons, 74, and Myra Thompson, 59, according to NPR.

Roof attacked the storied, historically black church because he wanted to start a "race war," according to media reports. He is expected to have a bond hearing at 2 p.m. Eastern today. NBC News reports Roof told authorities he almost didn't go through with the killings because everyone at the church was so nice to him.
