A BBC team is due to start filming today in the Cranhill area of Glasgow where Jean Campbell died. The murder of the mother-of-two featured in a brief appeal in January but a longer, in-depth look at the crime is now planned for a future edition of the programme.
Mrs Campbell, 53, was attacked in Cranhill Park in the east end of Glasgow while walking her German shepherd Kia late at night on December 13 last year.
Husband John Campbell, 55, a production manager with Network Rail, found her body the next morning after finishing a night shift.
Since then, police have DNA-tested more than 1200 local people over the age of 12. Some have been detained and questioned but no one has yet been charged.
It is not known if the programme will feature any of Mr Campbell's family. Daughter Lianne, 34, son John Jr, 33, and husband John have never spoken about her murder.
While Crimewatch often stages dramatised reconstructions, it has not been confirmed if this will happen in the broadcast relating to Mrs Campbell.
A BBC spokeswoman said: "At this stage, we can't yet say exactly what form the appeal will take."
It is believed that the BBC plans to film from a tower block flat overlooking the park in which Mrs Campbell was murdered as well as in the Cranhill Premier Store which she used every day.
