Detectives soon discovered Haigh’s record of theft and fraud and searched the workshop. Police found Haigh’s attaché case containing a dry cleaner’s receipt for Mrs. Durand-Deacon’s coat, and also papers referring to the Hendersons and McSwans. The workshop in Sussex rented by Haigh did not contain a floor drain, unlike the workshop he had rented at Gloucester Road in London. He, therefore, disposed of the remains by pouring out the container on a rubble pile at the back of the property. Investigation of the area by pathologist Keith Simpson revealed 28 pounds of human body fat, part of a human foot, human gallstones and part of a denture which was later identified by Mrs. Durand-Deacon's dentist during the trial.
