Conversely, the archaeologist John Alexander believed that this damage resulted from a robbery by medieval treasure hunters. Supporting this idea is comparative evidence, with the Close Roll of 1237 ordering the opening of barrows on the Isle of Wight in search for treasure, a practice that may have spread to Kent around the same time. Alexander believed that the destruction may have been brought about by a special commissioner, highlighting that the "expertness and thoroughness of the robbery"—as evidenced at Chestnuts—would have necessitated resources beyond that which a local community could likely produce.
