The Alvarez incest case was uncovered late March 2009 when 59-year-old Arcedio Alvarez was arrested in Mariquita, Colombia, accused of imprisoning and sexually abusing his daughter Alba Nidia Alvarez over a period of 25 years, beginning from when she was 9 years old. The daughter also gave birth to 14 children, six of whom died. Alvarez has been named "The monster of Mariquita" by national press.
