Robert Thomson, 49, from Buckhaven, Fife, is charged with repeatedly stabbing and murdering his son and daughter.

Ryan Thomson, who was seven, and his 25-year-old sister Michelle were found at Muiredge Cottages in the town on Saturday evening. During his appearance at Kirkcaldy Sheriff Court Thomson made no plea and was remanded in custody.

He is expected to appear for full committal next Monday.

Thomson was discharged from Dunfermline’s Queen Margaret Hospital on Monday. He was taken to hospital for treatment following the discovery of the bodies.

Chief Inspector Andy Morris, of Fife Constabulary, described the incident as “a terrible tragedy which has shocked the entire community”.

Extra community officers were in the town to reassure residents. Meanwhile, teachers at Ryan’s school paid tribute to him.

Yvonne Menzies, headteacher at Buckhaven Primary School, said: “Ryan was a lovely little boy who was open and friendly.

“He was very popular in school and had a wide circle of friends. He and his friends loved to play imaginative games together.”
