A new forensic search of the home of missing university chef Claudia Lawrence is beginning as detectives launch a fresh review of the case.
The 35-year-old was reported missing four-and-a-half years ago after she failed to turn up for work at York University.
Despite a high profile investigation by North Yorkshire Police involving up to 100 officers, no trace of Miss Lawrence has ever been found.
Officers believe she has been murdered, but no body has ever been discovered.
