The story of a young mother who went missing from her home three years ago is to feature in a documentary.
Natalie's son Rhys was 11-weeks-old when she disappeared
Natalie Putt, originally from Aberystwyth, was 17 when she was last seen leaving her home in Gornal, in the Black Country, to go shopping in 2003.
Her family believe she would never have deliberately left her baby son Rhys.
Her case features in a BBC Three documentary called Runaways on Thursday. Her family hope it will help them find out what happened to her.
Her sister Rebecca Coggins said: "She was absolutely alive. There was no way on this earth that she would have left that baby, never."
Her father David Putt said: "Natalie was a good mum. She loved Rhys."
The programme is screened at 1930 GMT.
