At 03:50 on the 20th of November 92, the body of Natalie Pearman (16) was discovered by a lorry driver in a lay-by at Ringland Road, Norwich. Natalie had last been seen alive just hours earlier at 01:15 on Rouen Road.
A post-mortem examination found the 16-year-old, who has been working as a sex worker, was asphyxiated. Police also said there were signs of sexual activity shortly before her death. At the time of the initial investigation, DNA samples were taken but no match has yet been found.
Police have DNA-profiled nearly 700 men and interviewed more than 4,000 people in the case. They also ruled out 5 persons of interest in 2018.
