Trial of the Lestranges and Bartemius Crouch Junior

The trial of the Lestranges and Bartemius Crouch Junior occurred before the Council of Magical Law at some point in December 1981. The accused were Crouch Jr. and three members of the Lestrange family: Rodolphus Lestrange as well as his brother Rabastan and wife Bellatrix, who had tortured Frank Longbottom|Frank]] and Alice Longbottom into insanity.

The Trial
Rodolphus Lestrange, Rabastan Lestrange, Bellatrix Lestrange and Bartemius Crouch Junior were brought in front of the Council of Magical Law when they tortured Frank and Alice with the Cruciatus Curse while they tried to find Voldemort.

During the trial Crouch Sr.'s wife/Crouch Jr.'s mother was present as well, who sobbed into a handkerchief.

A trial being the closest to fatherly affection he can give, Crouch did not make any difference for it despite his son being among the convicts. Ignoring his son and wife's pleas, as well as the apparently not completely certain evidence that his son was guilty in the first place (it was later stated that there was some ambiguity about whether his son had taken part in the torture or merely been in the wrong place at the wrong time), he sentenced all four Death Eaters to Azkaban for life, while cruelly claiming that he has no son: his decision was met with the roaring approval of the court. In Sirius's opinion, and by all accounts, this court was nothing more than a sham trial for Crouch Snr to express his hatred for his son and to publicly disown him in front of the entire Wizengamot.

Outcome
Crouch Jr.'s mother was dying from stress and as a last favour to her, her husband offered to release their son. Later, with the use of Polyjuice Potion, she turned into her son and took his place in Azkaban, while Crouch Jr. took a potion to look like her and she died in Azkaban and was buried beside the prison, bearing her son's name and appearance.

Then, years later at Hogwarts School of Witchcraft and Wizardry, Crouch Jr. (who was disguised as Alastor Moody) finally got his revenge by killing his father with great pleasure, then turning his body into a bone and then burying it in Rubeus Hagrid's Rubeus Hagrid's garden.
