One of Ireland's youngest killers has been sentenced to life imprisonment for the murder of schoolgirl Ana Kriegel.
Two 15-year-old boys, known as Boy A and Boy B, were found guilty in June of murdering the 14-year-old.
The schoolgirl's naked body was found in an abandoned farmhouse in Lucan, Co Dublin, last May after she had been reported missing by her parents.
Boy A was also convicted of aggravated sexual assault and was sentenced at Dublin's Central Criminal Court on Tuesday to life, with a review period after 12 years.
Boy B was sentenced to 15 years' detention, with a review after eight years.
A post-mortem examination found Ana suffered head and neck injuries and there was attempted penetration of her vagina.
Semen staining on a top found at the scene where the schoolgirl's body was discovered contained the DNA of Boy A.
Both boys have been granted lifelong anonymity due to their age.
