A former Van Alstyne substitute teacher was taken into custody Wednesday after being convicted of distributing harmful material to a minor.

Kristen Lynn Jackson faces up to a year in state jail and a $4,000 fine for the offense. The same jury that convicted her Wednesday will consider what punishment she should face on Thursday. Testimony in the penalty phase begins at 9 a.m. Thursday in Judge Carol Siebman’s County Court-at-Law 2.

Jackson testified that she did send a video and photo of herself that included content of which she is not proud. However, she said, she meant to send it to a grown man who had a similar name to the teen who evidently received it.

That teen, now a 17-year-old Van Alstyne junior, testified that he was on his way to the school’s “open gym” back in June of 2016 when he received a Snapchat from Jackson. He said the two exchanged texts and then he asked her to send him a photo of her tattoos. Instead, he said, he got a photo that showed her “tramp stamp” and her naked buttocks. Shortly after that, he said, he got a video that showed the naked woman masturbating. He said he could see her face in the video so he knew it was his former substitute teacher.

He said the video made him uncomfortable. He showed it to a friend who was at the gym and soon, he said, word about the video got around town. He told him mom and stepdad about it. The teen testified that the photo and video were not the first times that Jackson had been inappropriate toward him. He said she asked him pointed questions about his sex life while she subbed for one of his teachers. When asked specifically what she wanted to know, the teen said, “What we’ve done — like sexual wise.”

Jackson said she overheard that student and others discussing the relationship.

The teen said Jackson also approached him at a basketball game and sat down so close to him that he moved because it made him uncomfortable. He said she then moved closer and put her hand on his thigh before asking him, if she made him nervous. Jackson denied that ever happened.

In addition to the testimony from the two teens who claimed to have seen the Snapchat before it disappeared, jurors also watched a video of Jackson talking to a police officer in Van Alstyne and heard from the mother of the teen who received the photo and video.

The mom said when she heard about the material her son had received, she went to Jackson’s house and told her to stop communicating with her son. The mom said she told Jackson if she didn’t comply, “I would come to her house and beat her a—.”

The mother said Jackson said she didn’t have Snapchat and didn’t send the messages.

On the stand, Jackson, a 36-year-old mother of seven kids ranging in age from 21 to 9 said she did send some photos that day but she meant to send them to a man she knew in Howe, the city where she grew up. She said she wasn’t proud of that considering she is a married woman, but she didn’t mean for them to go to a child. She claimed the teens asked her to be their friend on social media and that she deleted them as contacts soon after.

At the end of the day long hearing, Assistant Grayson County District Attorney Matt Rolston said it all came down to who the jurors found more credible. He said the teens had no reason to lie about their interaction with the substitute.

Jackson was represented in the case by Sherman attorney Micah Belden.
