A mother who stabbed her three young children to death has been found dead in a high security hospital.
Theresa Riggi, 50, was jailed for 16 years for killing her eight-year-old twins Austin and Luke and her five-year-old daughter Cecilia at their Edinburgh home in August 2010.
Riggi moved to the UK in 1998 with her husband Pasquale, a Shell employee from Colorado, living for several years in Corton, near Lowestoft, before moving to Scotland in February 2007. She and her husband later separated.
Her children’s bloodstained bodies were discovered lying side by side in their Slateford Road home following a gas explosion at the building, each with eight stab wounds.
Riggi was initially charged with murder but admitted three counts of the lesser charge of culpable homicide on the grounds of diminished responsibility.
A court heard that a report into her mental state identified narcissistic, paranoid and hysterical personality disorders.
She was moved from the all-female Cornton Vale Prison, near Stirling, after a string of alleged attacks in 2011.
The US-born Riggi was found dead at Rampton Secure Hospital in Nottinghamshire today.
A Nottinghamshire Police spokesman said: “We can confirm that we were called to Rampton in the early hours of this morning to the death of a woman. It’s not being treated as suspicious and we are preparing a file for the coroner.”
