girl lodged a complaint in the nearest police station. Police reached to this
house and found the boy alone in his house/flat. On questioning about the
whereabouts of the girl, he tried to mislead them. While police were searching
his house, a nearby shopkeeper arrived and informed to the police present there
that the boy was seen purchasing a big knife few days back. On searching the
house, the fridge was opened and all were surprised to see a body cut into
several parts and stored properly. While questioning the boy, first he replied
he was not aware of this as he was out of station and produced bus tickets

revealed that he killed the girl and preserved body pieces in fridge so that he
could dispose them gradually so that people do not suspect him.
