Amanda EdwardsWiltshire, UK
A female was abducted by her ex-boyfriend. Intelligence suggested that her ex-boy friend had taken her to his house. A search by the EVRD of the house resulted in small blood stains being alert indicated and forensically confirmed as her blood. The suspect, a builder, was in possession of a van. This was searched and the EVRD dog alerted to a 'wacker plate', spirtit level, and shovel. A site was identified where the suspect had been working. The EVRD then located the body deposition site in an area of a garbage base that had been prepared by the suspect. He had returned with the dead girl, dug a grave in the centre, placed the body in the hole, replaced the spoil and then used the shovel, wacker plate and spirit level to return the ground to its original state.
https://www.mccannpjfiles.co.uk/PJ/MARTIN_GRIMES.htmOn the late afternoon of April 15, while Cortis remained in custody, tracker dogs drew officers' attention to a spot on a building site where Cortis had worked as a plasterer.
A tent was set up over the area and police intended to come back the next day to dig.
The maximum period for which police can keep a person in custody is 96 hours, but Cortis was released after 78 hours in the early morning of April 16 as they did not consider they had enough evidence to charge him.
He was found hanging at 1.25pm by his mother-in-law, Theresa Tavener. Twenty minutes later at the building site police found a plastic sheet which had contained a new mattress which Cortis bought after the murder.
Later when the plastic sheet was removed it was found to contain Miss Edwards' body, her wrists and ankes bound with tape.
