Crystal Thompson, author of the That Got Dark newsletter, BuzzFeed's weekly roundup of creepy, macabre, and horrible content. This week, she highlighted a disturbing video showing a basement where dozens of unidentified male pledges were held motionless by police. The video is tied to alleged fraternity hazing at the University of Iowa and has been viewed as disturbing. Other dark stories included a man who cut off his own arm to save his life by using a power saw blade to cut through it, and a man identified as Joseph Tine appeared at the site carrying a pistol. The missing persons case of Michael Larry "Mike" Madden, a 20-year-old California man who disappeared from the Stanislaus National Forest in 1996, was also mentioned. Despite extensive searches, no trace of the missing person has ever been found.
