A former high school teacher in Kansas has pleaded guilty to unlawful sexual relations with students.

28-year-old Michelle Preston, a former freshman cheerleading coach and psychology teacher at Shawnee Mission West High School, is alleged to have had sexual relations with three male students occurring between September and December 2010.

Prosecutors said DNA evidence links one of the boys to a sofa in Preston’s home. Preston is alleged to have initiated contact with the students through Facebook.

A police investigation was launched in March 2011  after naked photos of Preston began circulating amongst students.

According to multiple sources, she is likely to receive probation and be forced to register as a sex offender, although jail time is still a possibility.
