The doctor apparently left his home in Seville in 1995 during a bout of severe depression to live as a hermit in Maremma, Tuscany. He was declared dead 14 years later after his whereabouts were unknown.

His mother Amelia added: "We respect his will and his freedom but we're not leaving until we have held him in our arms again - even if it is just for one last time."
