Anastasia "Ana" Kriégel was a Russian-Irish girl who was subject to a violent attack, murder and sexual assault in an abandoned house in May 2018 in Lucan near Dublin. Two boys, known only as Boy A and Boy B, who were 13 years old at the time of Kriégel's death, were convicted of her murder, with one of the boys being further convicted of aggravated sexual assault. The two convicts are the youngest in the history of Ireland to be charged with murder.
