A Florida high school teacher charged earlier this year for a sexual relationship with one of her students not only allegedly confessed to the felony, she toured cops through her classroom to point out where the crime occurred.

The tour by Heather Mashburn-Smith, 37, arrested in late April, was revealed Thursday in a police body cam video obtained by Law & Crime as the teacher candidly tells in graphic detail where and how she had sex with the 17-year-old student.

Charlotte County Sheriff’s Office Major Crimes Unit he teacher was arrested in late April and charged her with Unlawful Activity With a Minor, a first-degree felony because of her position of authority as a teacher.

Mashburn-Smith taught at Port Charlotte High School. The school has an enrollment of nearly 1700 students and is located in Port Charlotte, a city of about 60,000 located halfway between Sarasota and Fort Meyer’s on Florida’s Gulf Coast.

“Can you just show us where in the room the sexual activity took place?” a deputy from the sheriff’s office asks the teacher, as revealed in the footage.

Mashburn-Smith walks the officers to the back of the classroom and points to a pair of desks.

“I feel like it was these desks,” the teacher says. “I’m pretty sure it was these ones.”

“As far as the intercourse goes, this is the desk that we leaned back on,” she continued moments later.

Then she described in detail the position they took in order to have sex.

According to court documents, the affair began with flirting over Snapchat after the teen called her “pretty,” the New York Post reported.

One thing led to another, resulting in sex in her classroom at least twice, according to her arrest affidavit.

The teacher is seen in the footage admitting that she would leave the side door to her room cracked so the boy could come in after football practice, or, he’d knock and she’d let him in.

She told police in the video that the sex was not planned out.

“It’s not like I let him in and we went right to it or anything,” she tells the deputies. “We would hug and talk… like I said it was not premeditated sex.”

At the conclusion of the video, deputies place Mashburn-Smith in handcuffs and transport her to the police station.

As previously reported by the Post and local news outlets, the teacher told the boy she wanted to “leave her husband for him when he turned 18, the legal age of consent in Florida,” according to charging documents.

But any future for the two ended when the teen stopped chatting with her and blocked her on Snapchat, according to the affidavit.

Mashburn-Smith’s confession, which reportedly came after she was given her Miranda warnings that outline her rights, disclosed the affair to investigators, saying that she “made a mistake,” according to documents filed in court.

The charge against the teacher carries up to a maximum sentence of 30 years in prison upon conviction. With her trial pending, it is not clear whether she has remained in jail or is out on bond.

The ability for teachers and students to communicate secretly on the internet is one of the enabling factors creating an epidemic of “educator sexual misconducts” cases throughout the U.S., according to an exclusive Breitbart News investigation earlier this year.

What leading researchers called “rampant” teacher sexual abuse in the past two decades has also been fostered by a “culture of permissiveness” in schools and the reluctance of employees to report their colleagues for suspicious behavior so as not to upset the harmony among staff, experts told Breitbart News.

Cases pop up weekly throughout the U.S. from school districts large and small, public and private. They not only involve female teachers and teen males, which generate the sensational headlines, but also embroil male teachers and minor females, Breitbart News found.

Partly triggered by that disturbing trend, 15 states have now passed “anti-grooming” laws, which seek to spot and arrest adults before sexual activity takes place in effort so spare minors the emotional damage that results.
