The Aguilar de Campoo case refers to the disappearance of Virginia Guerrero Espejo and Manuela Torres Bouggefa, two teenaged girls, on April 23, 1992.
Guerrero (14) and Torres (13) were last seen hitchhiking from the municipality of Reinosa, Cantabria, to their hometown of Aguilar de Campoo, Palencia.
[2] On the afternoon of April 23, 1992, Virginia Guerrero had asked her mother, Trinidad Espejo Muñoz, for money to buy a cake for a birthday party she was going to attend.
Instead, the two girls apparently took a train to Reinosa (a small town located 32 kilometres (20 miles) north of Aguilar de Campoo) to go to a nightclub, without telling their families.
[2] On 9 October 1994, two bags containing human bones were found in the countryside near the Requejada dam (a few kilometres north-west of Aguilar de Campóo), but forensic investigations ruled out the possibility of them belonging to the girls: instead, they belonged to unknown victims of the Spanish Civil War, which was waged between 1936 and 1939.
