Gellert Grindelwald's extradition

The Gellert Grindelwald's extradition occurred on 30th May 1927. Gellert Grindelwald was supposed to be transported from MACUSA's prison to Europe by Rudolph Spielman and Aurors to answer for crimes he committed. Because of his gift of persuasion, he had his tongue cut out, as several guards had sided with him. Unbeknownst to Picquery, Spielman and others, Abernathy, MACUSA's employee, was one of Grindelwald's acolytes. A few moments before escorting the dark wizard, Abernathy went to Grindelwald's cell and they both assumed each other's identity. When the flying Incarceration Carriage with Abernathy (as Grindelwald) set off, Grindelwald (as Abernathy) apparated onto the carriage and killed the Aurors escorting the carriage. Later, he entered the carriage and threw Spielman into the New York's waters, before flying to Europe with his lieutenant.
