Seven people – Margaret Lang, John Lindsay, James Lindsay, John Reid, Catherine Campbell, Margaret Fulton, and Agnes Naismith – were found guilty of having bewitched Shaw. Reid committed suicide by hanging himself in his prison cell, using his handkerchief attached to a nail in the wall. The other six were hanged and then burnt on the Gallow Green in Paisley on 10 June 1697,[2] the last mass execution for witchcraft in western Europe.[3]
