The actual story is ...

The actual story is something else. The three sisters had neither biological mother nor father, both were step parents. The so called family friend was the main culprit. Rumours are around that it was a well planned job and the three sisters unfortunately went to the Malake island with the culprit, not knowing what was waiting for them. According to rumours, there are more people involved including big guns, who have sold the girls as sex-slaves to foreigners. The step-relatives became rich overnight, is questionable (did get huge sums) and I suggest Police to look deep in the matter. Why another girl disappeared prior to these three girls kidnapping, seems the team working as a mafia gang.
