On the night of 13th November 1985, the Nevado del Ruiz volcano in Colombia erupted, and the resulting landslide of mud and debris devastated the nearby city of Armero, causing twenty thousand deaths in the city itself and a further 5,000 in the wider area. In the aftermath, a baby called Jennifer was left with the Red Cross by her mother, who is then believed to have ventured back to the ruins of the family home to search for her partner. She never returned. BBC Mundo's Jose Carlos Cueto tells the story of Jennifer, who has become known as the 'daughter of the volcano' and continues to search for the truth about her mother.
