"It was hard to make friends here because I had moved all over teaching," she told the police. "I was like really, really lonely." She became involved with an exclusive group called the In-Crowd. They were affluent, attractive and hedonistic. They partied most nights, got riotously drunk and had lots of sex. Their average age was 15. She was 26 - more than 10 years older than most of them - but no one seemed to care.
