Pedro Alonso López, the 'monster of the Andes' who murdered more than 300 girls and disappeared 23 years ago without a trace
He lived on the streets of Bogotá, was in Ayacucho where he abducted and killed several girls and was captured in Ambato when he wanted to kidnap a minor. He was released in 1998 from the psychiatric center because he was “healthy”. Interpol is still looking for him, but his whereabouts are unknown.
