A former Oklahoma high school teacher was charged with rape and sexual battery for having sex with three minor students. On Friday, a grand jury indicted Janet Kaye Barnes.

According to the indictment from the Supreme Court of Oklahoma, the 44-year-old teacher was accused of having sex with multiple minors between 2014 and 2016. She allegedly had sex with two separate minors between January 2014 and November 2016 while she worked at Pocola High School.

Barnes was facing two second-degree rape charges for each incident. She was also accused of committing sexual battery against another minor, unrelated to the ones she was accused of raping.

According to local reports, Barnes no longer works at the high school.

A LeFlore County judge signed a warrant for her arrest and set her bail at $250,000, according to court documents. In Oklahoma, second-degree rape carries no less than one year and no more than 15 years in prison. The sexual battery charge carries no more than 10 years of imprisonment.

There have been several cases in the past where teachers were arrested and charged for having sex with minor students. 

Last week, a former teacher in Waterloo was charged with having sexual contact with a teenager, the New York State Police said. The victim told police that the 29-year-old teacher, identified as Lindsey M. Halstead of East Bloomfield, sent him nude photos on SnapChat before meeting him up for sex.

Halstead, who worked as a gym teacher at Waterloo High School, faced two counts of sexual misconduct and one count of endangering the welfare of a child, both misdemeanors. 

In another case, a public school teacher in Sulphur, Louisiana, was accused of raping a 10-year-old boy. Deidre R. Smith, 34, a teacher at Lake Charles Charter Academy, was arrested after the Calcasieu Parish Sheriff’s Office received a tip regarding the woman “possibly having an inappropriate relationship” with one of her students. Smith was charged with first-degree rape and felony indecent behavior with a juvenile.
