This is bizarre. Presuming that they were adults, what in the world is a 13-year-old doing in any sort of 'relationship' with three men??
Maybe cause she doesn't have a daddy in her life? I don't know - just my take on it.
Maybe like her teacher or neighbor or coach -- people who might know where she would go if she wanted to run away.
Which leads me to believe that authorities thought this was a runaway rather than an abduction.
