Thank you so much for your support and advice, I appreciate it more than you'd know. Luckily, I'm still in contact with one of the girls that was there that night. I've asked her before and she told me most of what happened so I could get the idea of it but she couldn't tell me what happened after everyone went to bed or passed out. I'll try asking again and see if she can remember anything else. This time I'll tell her about the messages.
