Myallstarz,
It saddens me to hear of what happened to your daughter. I hate to see something like this happen to a kid. There are just some real jerks out there. My four year old had his back pack filled with his favorite toys stolen from a softball park a couple of months ago. I guess you can expect some young adult to do something like this, but what adult would steal from a child.
Please make sure your DD knows there are way many more good people out there then bad.
