Mackenzie Crook made a public plea to help find his missing sister-in-law.
The actor joined Good Morning Britain to share more information regarding his family member's disappearance. Laurel Aldridge, 62, was last seen a week ago in the vicinity of the cricket ground in the West Sussex village of Slindon, but no one has managed to make contact with her since.
Discussing a potential reason for her disappearance, he said: "She was diagnosed with cancer last year and she missed, I think, a fifth chemo session last Tuesday. We think that's triggered some sort of crisis in her and she's gone off for a long walk somewhere and that's the last we've heard of her. We're really clutching at straws now after a week."
