Pandolfi killed Marquett in Messina on 21 December 1675 following a political argument in the Duomo. Pandolfi is described in a contemporary chronicle as a "priest of Montepulciano", and Marquett as "an impertinent layman and eunuch". It reports that Pandolfi had seized Marquett's sword and killed him with it. After this Pandolfi fled first either to France or Catania, and then to Spain, where he was employed from 1678 in the Royal Chapel. He visited Rome in 1679. In 1682 he is reported as living in the household of the Papal nuncio in Madrid, Savo Mellini.McCormick (2011), p. 18. There are no references to him after the year 1687, which may be the year of his death.
