The mum of a seven-year-old girl who was murdered more than 30 years ago has demanded a public inquiry into police failures.
Nikki Allan was struck with a brick and stabbed 37 times by David Boyd in Sunderland on October 7, 1992. The young girl's body was found in a derelict building, known as the Old Exchange.
Boyd, 55, has evaded justice for 31 years. Advances in DNA in recent years led police to him and was he convicted of her Nikki's murder by a jury at Newcastle Crown Court on Friday, May 12.
