A reconstruction of the last known movements of a grandmother who was murdered almost five months ago while walking her dog has been shown on BBC's Crimewatch.

Actors portrayed Jean Campbell, 53, who was killed in Cranhill Park, Glasgow, on December 14 in last night's show.

Her body was discovered at about 7.40am the next day by her husband after he returned from work.

Mrs Campbell's tearful daughter, Lianne, 34, told viewers: "My dad always walked the dog before work. But I do know, obviously later on that night, she's taken the dog out twice, for whatever reason. And the second time, she never made it home."

A detective also urged viewers to come forward with information.

An appeal was also made on the programme by the children of former Borders-based artist Valerie Graves, who was bludgeoned death as she house-sat at a luxury property in Bosham, West Sussex, on December 30. The 55-year-old moved back to the area from Jedburgh.
