Even weirder is that her Dad logged into her Myspace account AFTER her death, found the message which believes CAUSED her death and wants to be the basis of a criminal prosecution but he can't remember exactly what it said, didn't notify the authorities and didn't bother saving it to the local machine. and now the police can't find it anywhere. He coincidentally appears to have mentioned this message after destroying the other parents property.
So there's no proof the other parents did anything apart from admitting to creating a myspace account to find out what she was saying about their daughter. So we have no proof none of this ever really happened as told by Megan's parents.
