Harry said, "Sonorus. A few days ago, I received a tip that Demodocus Cooper and some Death Eaters would attack the new school that Hermione and I are attending, Manchester Magical Academy. Yesterday, Cooper and the Death Eaters attacked. Our side suffered only one death, but the MMA professors and Hermione killed Cooper and all of the Death Eaters. When I went through Cooper’s pockets, I found this letter, written by Dumbledore."
