On 17 January 1670, judge Sir William Morton found him guilty of six robberies (others remained unproven) and sentenced him to death. Despite many attempts to intercede, the King did not pardon him and he was executed on 21 January at Tyburn. When his body was cut down and exhibited in Tangier Tavern, it drew a large crowd. It is traditionally thought Du Val was buried under the centre aisle of the church of St Paul's, Covent Garden; the parish register notes the burial of a "Peter Duval" in January 1670.
