A murder investigation has been launched after a teenage girl’s body was discovered in a disused farmhouse in Ireland.

Anastasia Kriegel’s body was discovered in the property near Lucan village in County Dublin on Thursday afternoon.

The Garda Síochána launched the murder inquiry after a postmortem on Friday morning to determine the cause of the 14-year-old’s death.

Anastasia had been missing from her home in nearby Leixlip since Monday. She was last seen at St Catherine’s Park, near Lucan, at about 5.30pm on Monday.

The 200-acre park is about half a mile from the farmhouse in Clonee Road.

Gardaí are investigating whether Anastasia was alone at the time she went missing and have appealed for information.

Supt John Gordon said Anastasia’s family was “extremely distressed”.

Clonee Road remains closed as a forensic examination of the crime scene continues.
