Antonin Dolohov

Antonin Dolohov was one of the original Death Eaters of Lord Voldemort and was captured before Igor Karkaroff's trial and sent to Azkaban prison.

In 1995, Dolohov, along with the Lestranges and several other Death Eater convicts, escaped Azkaban and rejoined Voldemort. At the Battle of the Department of Mysteries, Antonin Dolohov badly injured Hermione Granger with an unnamed spell.

He was the wizard who murdered Gideon Prewett and Fabian Prewett, Molly Weasley (formerly Prewett)'s brothers.

In the battle, he was struck with a Full Body-Bind by Harry Potter and was presumably captured in the aftermath of the battle by Aurors

In Harry Potter and the Deathly Hallows, he killed Remus Lupin while dueling with him (and Tonks being killed by Bellatrix nearby). He was later defeated by Professor Flitwick, as it is stated he fell with a scream it is most probable he was killed by the charms professor.
