Mother admits killing her three children

An American woman has admitted killing her three children in Edinburgh last year.

Theresa Riggi stabbed her eight-year-old twins Austin and Luke and their five-year-old sister Cecilia at their home in the city.

Their 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.
