Police: Ex-kindergarten teacher had sex with two high school students at once

A former Texas kindergarten teacher was arrested over the weekend after allegedly having sex with multiple high school students.

Heather Robertson, 38, is accused of improper relationship with four teen boys, two of whom she allegedly had sex with at the same time in her Lufkin home.

According to police, one of the students told them that he and Robertson began "sexting" on Snapchat after spring break,

Her arrest warrant states that Robertson asked the boy to come over to her apartment to have sex. When the boy told Robertson that a friend was with him, he told police she said the friend could come over, too.

Once at the apartment, Robertson allegedly asked them to have sex with her. According to the warrant, Robertson told them to follow her to her bedroom, where she began taking off her clothes before having sex with both boys.

Following her arrest, police interviewed Robertson, who allegedly told them she did not use condoms when she had sex with the boys because she can no longer have children, reports the Lufkin Daily News.

Two other boys have allegedly come forward with claims they had sex with Robertson.

In the interview, cops say said the first sexual encounter occurred in late 2016 and that the last time was April 14.

She also admitted to having sex with the two students at the same time, but said it was the only time she was sexually involved with those boys.

Following the arrest, Robertson's former employer, the Hudson Independent School District, released a statement saying the kindergarten teacher had resigned.

"We acted immediately and began our investigation," Superintendent Whiteker said. "We pursued with the correct protocol we have to follow. I accepted the resignation (Thursday) afternoon, and it has been submitted through the appropriate legal channels. Our investigation has been finalized."

Robertson could face up to 20 years in prison if convicted.
