A woman who used to live at Corton, near Lowestoft, has admitted killing her three Norwich-born children.

Theresa Riggi appeared at the High Court Edinburgh today.

Riggi stabbed her eight-year-old twins Austin and Luke and their five-year-old sister Cecilia at their Edinburgh home.

The children's bodies were discovered following a suspected gas explosion in August last year at the townhouse they shared with Riggi, originally from the States, in the Scottish capital's Slateford Road.

At the city's High Court today, Riggi, 47, entered a plea of guilty to the culpable homicide of her three children on the grounds of diminished responsibility. She had originally been charged with murder.

The children were born in Norwich and had lived with their parents - Riggi and her husband Pasquale - for several years at Corton.

Shell employee Mr Riggi, who hails from Colorado, and his wife, from California, came to the UK more than ten years ago. The oil engineer was based at Shell in Lowestoft from 1997 to 2002.

After living near Lowestoft, the family spent two years in Holland before moving to Aberdeen in February 2007. However Mr and Mrs Riggi later separated and had begun divorce proceedings.
