  1. I wonder was there background check to seeing house that campground don’t take those kind of people that’s what they told me

    1. Of course there was. This is true they don’t take most people with a background. The man didn’t live there and yeah your grammar sucks. Go back to school and stop being so nosy.

  2. Why waste the time & money to fly the POS out? So he can live another day to go to court where he will most likely get off anyway for stabbing someone.

      1. Nope they transported the suspect to DC by helicopter the patient went by ambulance

        1. That is exactly what I said, you just reversed it. Oh man, you are really something.

        2. You just said the same thing as Localboy (flew suspect, ground transport for victim), yet claim you are saying something different.

  3. I really hate to say this, however I know this boy. I do know that the campground did not want him there. However, a family member that lives there allowed him to stay with them. I hope and pray he stays in prison especially now that he has violated parole, yet again! He is a really messed up individual and doesn’t need to be subjected to society what so ever!
