DENISON, TX -- A former Denison ISD teacher was arrested after police say she admitted to having an improper relationship with one of her students.
Some of those encounters reportedly happened in the classroom.
"I've heard stories, like I've seen across the nation of it happening in other places, but I never expected it to happen here," said parent, Amy Timberlake.
Parents we spoke to say they can't believe 34-year-old Julie Bollinger, a former Denison High School teacher, was arrested for having an improper relationship with a student.
"It is a crime for a teacher to have a relationship with the teacher no matter what the age limit is," said Grayson County District Attorney, Joe Brown. "So the particular charge we are looking at in this case is an improper relationship between a student and a teacher."
An affidavit states that Bollinger resigned after she was confronted by Denison ISD administrators in May.
Bollinger didn't admit to having a sexual relationship with the student until after rumors surfaced in June that there was a video of the two having sex. It states that the day she resigned, she picked up the teen from church and drove him to a local hotel to have sex.
Denison ISD declined to comment on camera but did release a statement saying:
"As soon as the allegations came to our attention, we notified the Denison Police Department and turned the investigation over to our local police officials."
It also states they have informed the Texas State Board of Educator Certification of the relationship.
They say "it has been our objective from the beginning to follow he law and cooperate with officials in every way possible regarding this matter."
The affidavit also states Bollinger also bought an iPhone for the teen in order for them to communicate.
She told police that she also let the teen use that phone to film them having sex, but authorities say when they confiscated the phone from the teen, he said he'd deleted the video.
It also states that authorities found several letters between Bollinger and the student, including hall passes that Bollinger wrote to get the student out of class.
Bollinger admitted to having sex with the teen on multiple occasions, including in her classroom.
Denison Police say Bollinger has been staying with family in Coleman County and turned herself in to Sheriff's officials today.
She was later released on a $20,000 bond.
If convicted she could face up to 20 years in prison and a $10,000 fine.
