Police investigating the death of teenager Nicola Payne, who went missing in Coventry 21 years ago, are due to start searching an area of parkland in the city later today.
It's after detectives received new information in relation to her disappearance on her way home from her parents house in the Wood End area of the city in 1991.
Officers will use special equipment to X-ray the ground and metal detectors during the investigations.
The searches are expected to take several days to complete.
Over the years suspicion fell on several convicted killers but no evidence was ever found that she had been killed.
She was just 18 when she vanished, and had a seven-month-old son.
