A former finalist to be the 2025 Colorado Teacher of the Year will spend more than a decade behind bars after she sexually exploited a 16-year-old former student.
Tera Johnson-Swartz, 45, a former STEM Highlands Ranch teacher, was arrested in February 2025 on charges including kidnapping and contributing to the delinquency of a minor following a grand jury investigation into the relationship, according to an affidavit obtained by CBS News.
Another case was then filed against her after detectives learned she was trying to maintain contact with the teenager, who confirmed to investigators her attempts to talk to him.
She was then charged with sexual assault on a child by a person in a position of trust, and she ultimately pleaded guilty to sexual exploitation of a child and felony cybercrime, the Douglas County District Attorney's Office said.
Officials said the felony cybercrime charge stemmed from her continued contact with the minor, as she is accused of exchanging more than 2,400 texts with the student and taking him off campus in her personal vehicle, according to Fox News.
Prosecutors have said in early 2024, Johnson-Swartz initiated contact with the victim at the STEM School Highlands Ranch - a charter school within the Douglas County School District, by first sending him music.
Those text messages then progressed into texts 'discussing how and what they were doing.'
As the investigation continued, the victim told investigators he first met Johnson-Swartz about a year and a half prior, when he had been in a small class she taught.
The relationship was finally uncovered in January 2025 by a therapist who reported it to Douglas County Human Services, and she was she was 'immediately put on paid administrative leave, denying access to our campus, electronic records and students,' the school's chief innovation officer, Matt Cartier told 9 News.

He noted that she worked at the charter school from 2022 through Valentine's Day 2025.
But less than one month later, school security cameras recorded the student leaving campus and getting into a vehicle resembling the one Johnson-Swartz drove.
The student later told investigators his former teacher picked him up from school and drove him to a nearby neighborhood.
Prosecutors also said Johnson-Swartz met the student off-campus in early 2025, when she provided the teen with cigarettes, smoked marijuana with him and sexually assaulted him during multiple encounters.
That incident triggered a grand jury investigation, and Johnson-Swartz was charged with felony kidnapping.
An affidavit also recommended three counts of sexual assault on a child and contributing to the delinquency of a minor. But the disgraced teacher posted a $100,000 bond with the help of a professional bondsperson and was released the next day.
Months later, over the July 4 weekend, the victim's parents told investigators they found deleted texts between their son and Johnson-Swartz and confronted their teen about it, Denver 7 reports.
In several of the messages, Johnson-Swartz even told the juvenile to delete the text messages, according to an arrest affidavit.
Authorities said Johnson-Swartz exchanged more than 2,400 texts with the student, some of which she instructed him to delete.
An ensuing investigation revealed that the student ran into his former teacher on two consecutive nights at Fiddler's Green, a Greenwood Village concert venue.
It is unclear whether the two planned to meet at the concert, but the affidavit obtained by CBS News notes that the band playing those nights was featured in the music the two had exchanged early in their relationship.
'Yeah, it was really weird,' the student later told investigators, according to court documents. 'I was going there, expecting to have a great time. And then I just see her in front of the line, like 30 feet up, it was really weird.'
The two wound up speaking briefly on the second night, when the student claimed his former teacher told him, 'Just say you don't love me.'
In the aftermath, prosecutors said Johnson-Swartz began calling and texting her former student in the days that followed.
At that point, Douglas County deputies took Johnson-Swartz into custody again, this time outside of a fast food restaurant where she was working as a cashier.
She was then denied bond and remained in jail, before pleading guilty to the alleged crime.
In court documents, the student said he was not surprised Johnson-Swartz struggled to stay away, calling her an 'unstable woman.'
'She threw away her entire life for me. And I'm not entirely surprised by the fact that she then would have trouble letting go, because she did throw her life for me.'
He then denied that he ever told his former teacher he loved her 'and she never said that to me.'
'She is pretty stupid, I'm not going to lie,' the student told investigators. 'Already ruined her life and she keeps just making it worse.'

In addition to her lengthy prison sentence, Johnson-Swartz must now submit to six years of sex offender probation upon her release, and register as a sex offender.
Her arrest marked the fourth teacher convicted of a felony sex offense by Douglas County officials since a dedicated unit came into existence last year, according to KDVR.
'So far, all have been incarcerated,' District Attorney George Brauchler said in a statement.
'This warning is coming from a DA and a parent: if a teacher in our community exploits their position of trust with our kids for their own lascivious desires, we will seek to change their life forever,' he said.
'We will work to make them a convicted felon and we will try to take away their freedom.'
'Here, this predator stated at her sentencing that the conduct will not define who she is,' the District Attorney continued. 'I disagree. She is now a convicted sex offender and will live with that label for decades.'
Doulgas County Sheriff Darren Weekly added that authorities 'are grateful for the tireless work of our Special Victims Unit and the dedication of the District Attorney's Office taking this case so seriously.'
'Their commitment ensures that those who prey on our most vulnerable - our children - are held fully accountable.'
He added that 'protecting our youth will always remain one of our top priorities.'
