 The last trial and acquittal was in 1378, although the case had long-term consequences.No motive has been established for de Cantilupe's killing; historians consider it most likely that responsibility rested with de Cantilupe's wife, her lover, the cook and their neighbour, with a mix of motives including love and revenge.The de Cantilupes were a long-established Lincolnshire family based at Scotton in the northeast of the county.
