Jailed killer mother is moved after ‘attacks’

Theresa Riggi, 47, was jailed for 16 years in April for killing her eight-year-old twins Austin and Luke and her five-year-old daughter Cecilia at their Edinburgh home on August 4 last year.

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 Riggi’s mental state identified narcissistic, paranoid and hysterical personality disorders.

It is understood she is being moved from the all-female Cornton Vale Prison, near Stirling, to a psychiatric unit.

US-born Riggi is said to have been injured at the women’s prison when she was allegedly thrown down a flight of stairs on October 22. A fellow prisoner was arrested and charged in connection with the incident.

Central Scotland Police were also investigating a separate attack on Riggi, alleged to have happened on November 19.
