Inmate trial over alleged Theresa Riggi attack

Have your say

A WOMAN is to stand trial accused of slashing child killer Theresa Riggi with a razor blade in prison.

Angela Hamilton is alleged to have disfigured Riggi for life by slashing her face.

She allegedly pulled Riggi’s hair and repeatedly struck her face and head with the blade during an attack at Cornton Vale prison, near Stirling, in November 2011.

Riggi, 49, originally from California, is serving 16 years after admitting to stabbing her three young children at a house in Slateford Road.

Hamilton, 40, has denied the charge against her and is set to stand trial by jury at Falkirk Sheriff Court next week.

Riggi killed her three children, eight-year-old twins Austin and Gianluca, and their sister, Cecilia, five, in August 2010, stabbing each of them eight times. She then allegedly tried to cover up their deaths with a gas explosion, before trying to kill herself by leaping out of their flat.

Riggi admitted culpable homicide on the grounds of diminished responsibility.
