She could not find someone her own age? She could have easily slept with 20 something year old. Why choose a minor and risk your whole life?

http://newyork.cbslocal.com/2013/08/03/prosecutor-n-j-teacher-had-sexual-relationship-with-teenage-student/WALL, N.J. (AP) — Prosecutors say a central New Jersey teacher had a sexual relationship with a 15-year-old male student.
The Asbury Park Press reports 22-year-old Kalee Warnick of Wall was freed this week after posting $50,000 bail. She’s charged aggravated criminal sexual contact and having a sexual relationship with a minor she had care over.
Prosecutors declined to provide specific details on allegations, citing their ongoing investigation. They said authorities learned of the alleged relationship last month.
The newspaper reports that Warnick worked as a home instructor for the Wall school district. School officials said they were aware of the charges but declined comment on the matter, saying Warnick’s status would be discussed at a closed board meeting this coming week.
A telephone number for Warnick could not be located Saturday.
