People are mad at Sarah Fowlkes after her mugshot surfaced online...looking a little more like a smug shot.

So what could her crime be? A drunken night out with a bachelorette party? Maybe she was protesting something she truly believed in, so she's okay with the consequences?

Both of those would be better than the truth.

Fowlkes is facing up to 20 years in prison after being arrested on suspicion of sexual activity with a student.

She has been suspended from her job at Lockhart High School in Texas.

The mugshot was taken just hours after celebrating her birthday with her husband, but even still Fowlkes looks like she's having a great night. The police were notified about the inappropriate relationship because at the hand of a school administrator.

The 27-year-old is taking a lot of heat, not only for her alleged misconduct, but also because of her ear-to-ear grin. Does being arrested for a second-degree felony seem like something to be happy about?

According to her lawyer, Jason Nassour, says there's a really simple explanation to the smile.

"You've got a young lady who was arrested on the statement of a 17-year-old kid with no corroborating evidence," Nassour said. "This isn't a guilty person sitting there like they just got caught. When everything's fleshed out it won't be as it appears."

There's just one problem with that statement...police say they have found evidence of messages between her and the student. The messages are claimed to be in "sexual nature."

Local police officer Detective Jesse Bell said, "Seventeen years old is obviously older but at the same time it doesn't make anything right. If the kid is in school, parents trust the school to take care of their kids so it's definitely not right "” that a teacher in a position of power over a student be able to take advantage of a student."

The school board also released a statement on the subject:

"Parents entrust their children to us every day, and it is something  we do not take lightly. Student safety is the district's most  important priority. As soon as we learned of the report, we acted swiftly to involve law enforcement and CPS to conduct  a thorough  investigation. The district does not and will not tolerate any  improper communication or contact between a teacher and child."

Fowlkes has been married since 2013, no word yet on how the allegations have affected her marriage. I'm sure he doesn't think it's something to smile about though.

UPDATE:

The married Texas science teacher who grinned from ear to ear in her mugshot after she was arrested on suspicion of having sex with a 17-year-old student has submitted a guilty plea to a judge.

Sarah Fowlkes was arrested for allegedly having an illicit relationship with the unnamed student. She was charged with engaging in 'sexual contact with the intent to arouse or gratify the sexual desire of' the alleged victim.

Following her arrest, Fowlkes was suspended from her job at Lockhart High School in Texas.

Under terms of the proposal, she would be placed on deferred adjudication for four years, surrender her teacher's license and pay a fine, although the amount of the fine remains unclear.

"Under the circumstances, it is a situation where the deal isn't necessarily accepted so until it is accepted we don't know what it will ultimately be," her attorney, Jason Nassour, told KVUE. "If it is accepted, it will be based on the negotiation the state and I had."

Do you think it was inappropriate of her to smile in the mugshot? Let us know.
