The incidents began in 2012, according to court documents. Most of the incidents took place in Mesa's home in Fredericksburg, Va, and at least one incident took place in the teacher's SUV. The students range from 16-18 years in age, and two have admitted to having sex with the teacher. Mesa also reportedly sent nude photos of herself to students, and received nude photos from one student.

"I find it so difficult to understand how a situation could happen like this," retired teacher Molly Faulkner told Washington D.C. ABC affiliate WJLA.

Mesa is a geometry teacher at Colonial Forge High School, and has worked with the school district for five years. Her husband of two years, Keith Mesa, also works at the same high school as a social studies teacher. The couple coached the school's volleyball team together. Erica and Keith have been married since July 22, 2012.

Erica Mesa is now on administrative leave from the school pending the outcome of the case.
