It is presumed that, in Harry Potter and the Deathly Hallows Part 2, Bellatrix was the one who killed Tonks as in the book, since Tonks's death is never shown on-screen.n Harry Potter and the Order of the Phoenix, Bellatrix was broken out of Azkaban by Voldemort and some of his Death Eaters, along with Antonin Dolohov and many other Death Eaters.
