Professor Wilhelm Grumbly-Plank was a teacher at Hogwarts School of Witchcraft and Wizardry. On July 13, 2012, she was arrested for the murder of Professor Gordon Pummel. She murdered Pummel because she wanted his job, and she knew that everyone would think that Severus Snape murdered him. However, she couldn't scrape together an alibi for the time of the murder, and she was arrested in his place.
