Encounter with a Killer (1970)

In 1980, the capture of the infamous serial killer Pedro Alonso López, also known as the Monster or the Strangler of the Andes, seemed to end his nearly decade-long reign of terror. However, Ecuadorian laws benefited the murderer by giving him a shorter sentence and even the option of leaving in less time. When the Monster's release draws near, a group of family members struggle to find ways to keep him in jail, while he, from the inside, searches through a series of letters to clear his name and unmask the real killer: Jorge Patiño. The problem is that Jorge Patiño exists only in his mind.
