OLATHE, Kan. — “She was just the sweetest, caring, most loving child I have ever met.”

Those are the words of a grieving father who lost his 2-year-old daughter at their home in Gardner in February. Now, his ex-fiancée is charged with the little girl’s murder.

Lindsey Thomasson

Lindsey Thomasson, 24, was arrested Tuesday morning at her parents’ home in Ottawa. By noon, she was charged with first degree murder in the death of Presley Kay Porting.

The little girl’s father spoke to FOX 4 after Thomasson’s arrest, and said he is utterly heartbroken.

“I’m still an emotional wreck right now just missing my little girl. I’m so sorry, but I just cannot talk to you guys right now on camera,” he told FOX 4.

In photos, you can see Nick Russom like any dad: he loved playing, hugging, and sharing good times with his 2-year-old daughter, Pressley Porting.

“Pressley wold pat my back and hold my face and she was just– she was a wonderful, wonderful little girl,” Russom said. “She was my oldest daughter.”

In February, Nick said the unthinkable happened to his little girl at their home in Gardner.

“I had to go get some stuff from the store,” he recalled. “And we played a little bit and then I put Pressley to bed.”

2-year-old Presley Kay Porting died in February.

Nick said he and and Pressley’s 2-year-old sister left home and went to a grocery store.

He said his fiancée at the time Lindsey Thomasson and the couple’s 1-year-old daughter stayed home with Pressley.

Nick said when he returned and walked inside his house, he knew something was wrong.

“And I asked Lindsey to go get Pressley up from nap because I had a snack for her and that’s when Lindsey screamed my name and from there it just wasn’t good,” he recalled.

Police said Pressley wasn’t breathing, and later died at the hospital. An official cause of death has not been released.

“Again, I can’t talk about all that stuff right now because it’s still an ongoing investigation. I can tell you Presley was so well behaved. I mean, everything you asked her to do, she would do it because she was just the perfect little girl. As for Lindsey, I loved her more than anything in the world. I really did. I loved our family and for me, being there with her and my three daughters was the closest to heaven a man could be,” Nick said, fighting through the emotion.

When asked how he feels about Lindsey now, Nick said, “I can’t. I can’t talk about that. I’m sorry.”

The grieving dad said he has many unanswered questions surrounding his baby girl’s tragic death.

“I see guys with their daughters in the stores and I can’t even look at them without breaking down. I’ve been talking to my daughter all day just telling her to help her daddy get through this and help me be a better daddy to her sisters,” Nick added.

Thomasson is currently being held at the Johnson County jail with a $2 million bond.

She is scheduled to appear in court Wednesday.

Presley’s father, Nick Russom, set up a GoFundMe page, where it says that since the investigation he has lost his home, his job, his vehicle, and has also lost custody of his other two daughters.
