@farmerman,
The one thing is - this story because of all the media around it - has brought to life other missing persons - and so via social media people are using that to help find others.
As a result in the same area a man that had been missing - his body was found in the same area. After hearing about this girl - this missing man was posted and people called in or messaged in tips of seeing him in the area.
Maybe this will help others - maybe social media can be used in a positive light to help families find missing family members.
