The killing took place at a village near the town of Durres where Shaban Norja shot dead Aishe Vata, who was three-month-pregnant before cutting her head off and throwing it away in the hope that the body wouldn't be identified, reported Xinhua.
Norja confessed to police that he raped Aishe five years ago, adding they had maintained sexual relations afterwards. Aishe was pregnant with Norja before being killed.
Shaban's son, Nard Norja who migrated to Italy, feared a possible blood feud from Vata's family and decided to help the police, giving clear details about his father's whereabouts and the cabin where the crime was committed.
DNA tests confirmed that the 80-year-old is the father of the victim's child.
Many villagers still cannot believe that Norja is the murderer and said that they knew him as a respected and peaceful old man in the village.
