In October 2012, South Yorkshire Police began to follow a line of inquiry which suggested that Ben had been accidentally killed and buried in a mound of rubble by an excavator driver working in a field adjoining the house where he was last seen. Extensive excavation of the rubble was undertaken by British and Greek Police. One item of particular interest to the police was a Dinky toy car, which they hoped to recover and believed could be "key to discovering his fate." The search failed to detect any human remains or items belonging to Ben.
