An ITV documentary may have discovered structural anomalies within a cafe in Gloucester using Ground Penetrating Radar (GPR) in the search for Fred West victim Mary Bastholm.

According to ITV, film crews were using Ground Penetrating Radar (GPR) and sniffer dogs to look for human remains within the cellar at the Clean Plate Cafe in Gloucester. Mary's 1968 disappearance remains unsolved, however the 15 year old worked at the cafe where Fred West was a customer.

According to the Guardian, forensic archaeologists have confirmed that there are a number of structural anomalies within the cellar that warrant further exploration and excavation work will now begin.

Ground Penetrating Radar (GPR) identifies where the density of the ground differentiates between areas and these differing ground conditions or areas of differing densities provides us with anomalous areas, as shown by the examples below.

GPR & Buried Services

GPR for Voids

GPR for Building Lines

GPR for Buried Tanks

Given the right site conditions, GPR can be used to a depth of 0m to 6m (in theory), to detect features such as buried services and utilities, voiding & unconsolidated ground, saturated ground, tanks, foundations, air raid shelters, vaults & tombs, disturbed ground and a range of other features.
