From the York City Archives:

"After the execution the corpse of Turpin was brought to the Blue Boar, in Castlegate, where it remained till the next morning & then interred in the church-yard of St. George - the grave was made remarkably deep & the people who acted as mourners took such measures as they thought would secure the body, yet about three o'clock in the following morning some persons were observed in the church-yard, who carried it off."
