The teenaged girl who killed her mother's boyfriend in their Crestview home in the summer of 2009 likely had no idea what she was doing when she stabbed the man, according to the psychiatrist who assessed her after the fact.

The girl, who cannot be identified because she is a youth, was not suffering from a mental disorder when she stabbed her victim, Dr. Kulwant Riar told the court Thursday, "but at the time, she went into a rage – and out of rage, she acted against the victim.”

Her rage was not the normal anger experienced by people all the time, he said, but a temporary disassociated state, meaning she had no awareness of her actions.

"That's how rage operates,” he said. "The person does not know what they are doing.”

His assessment supported the girl's own testimony, also given yesterday.

She said she remembered coming home and going into the kitchen and the man following her in. He didn't touch her or say anything to her, she told the court, but he entered her personal space and she wanted him out.

"You have all day to come in here. Why do you have to choose this moment to do it?” she remembered thinking.

"... He just came too close and crossed my line – in my bubble and in my mind.

"... I guess I just decided to get a knife and – I don't know – like, hurt him, to get the message he'd gone too far.”

It was the culmination of years of resentment toward the man, which had grown into hatred.

He had moved into the family home about five years earlier after losing his apartment.

He worked for about a year, then lost his job and never got another.

He became increasingly sedentary, according to testimony from the girl's mother and brother. He didn't contribute any money to the household; he was grumpy and mean-spirited; he was psychologically abusive, the mother said.

"His contribution to the house deteriorated while his attitude and his use of things around the house increased,” the girl said when asked why she resented him so much.

He would sit in his chair and tell her and her brother to do things around the house, but he would never help out, she said.

He would ask the girl why she ate so much, and tell her she was fat. He made her friends uncomfortable and would never leave the living room so other people could watch TV or use the computer in private.

"I felt like he made me an intruder in my own home,” she said.

When prosecutor David McWhinnie pointed out that the girl didn't pay rent or buy groceries either, she said she had a part-time job and earned all her own spending money.

"I'm her daughter,” she said. "My mom doesn't have to buy me booze or smokes every two days.”

Although the girl and her brother both asked the mother to kick the man out on several occasions, he remained.

Eviction notices seemed to have no effect on him.

He spent every day sitting on "his” chair in the living room, smoking and drinking beer.

At around 1 a.m. on Aug. 8, 2009, the girl had come home after taking a lonely drive around town. She went to the fridge to get some juice, and her mother's boyfriend followed her into the tiny kitchen.

"Him coming into the kitchen just crossed a line, I think,” she told the court. "... He just got too close into my personal space.”

When asked what happened next, she said: "I just recall the turning around motion ... I don't recall getting or selecting a knife or hitting him.

"... The only thing I can recall (after that) is a picture ... of him on top of me. Not lying down, but like falling on me.”

She described the scene as if she was seeing it from outside her own body, a typical indicator of a dissociative experience, the psychiatrist said.

She stabbed the man 12 times, but said she had no memory of anything until she heard his breath whistling from one of the wounds in his back.

"It was a sound,” she said. "... there was a cut on his back and it was making a sound. Like a sound you've never heard before.”

She said she ran from the house and drove away in her mother's vehicle.

"I don't think I knew what I was doing,” she said when asked why she didn't go for help.

She immediately called her brother, and told him she had stabbed the man.

He headed back to the house, where he found the man still alive, but fatally wounded.

The siblings' mother, who had been asleep on the couch the whole time but woke up to the sound of her boyfriend calling for help, was also there when the paramedics arrived.

Meanwhile, the girl had gone to her best friend's house, called her mother, then went her boyfriend's place.

The girl was composed through her entire testimony, but began to cry when she described the phone call she made to her mother.

"I remember feeling scared my mom would disown me or abandon me ... that she wouldn't be my mom anymore.”

The court has heard testimony from her brother, best friend, boyfriend and mother, all of whom said the girl described details of the attack, including stabbing the man "50 times” and stabbing him in his chair, which she now says she cannot remember.

"It is possible for people in a panic to make statements that are not true and then not remember them after,” Dr. Riar testified, with her lawyer noting the victim was only stabbed 12 times, and there is no evidence to show he was in his chair when he was struck.

The girl has pleaded guilty to manslaughter, but is being tried for second-degree murder.

The difference between the two charges is intent: If the judge believes she meant to kill the man, or knew she was going to possibly kill him, then she is guilty of murder.

The girl gave her testimony in front of a courtroom packed with supporters Thursday. She said she hated the man who lived with her family, but didn't mean to kill him.

"I know that I meant to hurt him, but I didn't have intention to kill him,” she said. "... I still think to this day ... I did want him gone, but not like that.”

The trial ended this morning with Judge John Faulkner reserving his decision until March 30.

Because the accused is a minor, she cannot be identified, nor can the Star name her friends, family members and victim.
