As much as I hate to say it, IMO the drug references on here may have validity. I'm very familiar with this area and kids of that age. I've been trying to find the link desperately for the past 30 minutes... But, in something I read from the police this week they stated that kids were keeping quiet because they were scared to talk and get anyone in trouble. The police said that no one will be charged or investigated for the "things" they were doing that night. They said they are only focused on finding Christina. They stressed that anything illegal going on that night is not under investigation, they just need someone to open up and give some leads.
Also, her mom in the video about drones seems to have been told something that makes her believe Christina is still alive. After 2 weeks, it is hard to believe that someone is still alive without knowing more than we know. I know it's her mom and she is trying to stay strong. But something tells me she knows more. Have you guys seen the video?
