The conviction of David Boyd, more than 30 years after he killed schoolgirl Nikki Allan, has given fresh hope to the family of another murdered child.
Boyd was this week jailed for life after a jury found him guilty of killing seven-year-old Nikki in Sunderland in 1992.
The 55-year-old had escaped justice for more than three decades until a DNA breakthrough enabled detectives to link him to his horrific crime.
