A middle school teacher in North Carolina was charged for sending erotic pictures and videos to at least two former students, the New York Daily News reported.

On Tuesday, Caron Blanton, 34, turned herself into authorities after someone saw the content on a student's phone at Burns High School.

"It started out as a basic picture and then onto a bathing suit picture, and it ended up getting to the nudity and on into the video," Cleveland County Sheriff's Office Capt. Joel Shores told WSOC-TV.

Investigators also said Blanton sent students a video of her performing a sex act on herself.

The inappropriate images and videos occurred over a period of two years and began when the teens were in middle school, the Daily News said.

"There's no question in our mind who is in the video. Who made the video. We know exactly who was in the video," Shores said.

School officials learned on the situation on April 9. Shortly after, Blanton -- who worked as a sixth grade science teacher -- resigned from her job, the Cleveland County Sheriff's Office said.

Sheriff Alan Norman told WXII-TV there is no indication of any relationship between Blanton and either teen she corresponded with.

Blanton was charged with three counts of indecent liberties with a child under 16 and six counts of disseminating obscene material to a minor, according to the Charlotte Observer.

However, she is out of jail on $150,000 bond.
