Virginia Guerrero Espejo and Manuela Torres Bouggefa went missing on 23 April 1992 in Reinosa, Spain. Guerrero, then 14, and Torres, then 13, were last seen hitchhiking from Reinosa to their hometown of Aguilar de Campoo, Palencia, when they disappeared. Their case remains unsolved. The case is often linked to that of the Alcàsser Girls, who received significantly more media attention after their bodies were found, and is commonly called the Alcàsser case of Palencia.
