On June 2, Walter Lübcke was found dead in his garden with a bullet wound in the head. In his home town of Kassel, in the heart of Germany, the affable 65-year-old politician was a well-known member of Chancellor Angela Merkel’s center right party who had welcomed immigrants when she opened the country’s doors to refugees in 2015—and who had weathered a storm of hatred on social media as a result. Josephine Huetlin writes in the Daily Beast that at first, police insisted there was no political connection to the murder, and several investigators dismissed the possibility the killer came from the far right. But this week they arrested a suspect with neo-Nazi associations and a history of racist crimes. Now, the federal prosecutor’s office has taken over the case, which means it will be treated as an act of extremism and, in effect, of terrorism.
