Colombia's Dungeon Dad

In what is becoming one of the most disturbing trends in memory, yet another "dungeon dad" was discovered, this time in Colombia. Arcedio Alvarez, branded the "monster of Mariquita" (his hometown), is accused of raping and imprisoning his daughter, who is now in her 30s. Alvarez is said to have fathered 11 children with his daughter, three of whom died. The 59-year-old man claims that his daughter is adopted and that they had a consensual romantic relationship, though he his daughter says he raped her when she was only nine years old. Alvarez joins another alleged "dungeon dad" discovered yesterday in Italy.
