US: Ex-teacher gets 8-10 years for sex with student

A former Nebraska teacher who fled to Mexico with a 13-year-old student was sentenced Thursday to eight to 10 years in prison. Kelsey Peterson, 27, pleaded guilty in January to two state counts of first-degree sexual assault of a minor.

She is to serve her sentence simultaneously with a six-year federal prison sentence for transporting a minor across state lines to have sex. She also must register as a sex offender. Authorities said Peterson was the boy's sixth-grade math teacher at Lexington Middle School during the 2005-06 school year and started having sex with him in November 2006. (AP)
