KITCHENER -- WARNING: Some details may be disturbing to readers.

Several friends of the accused have testified in the trial of an Elmira teen accused of murdering his mother.

The court heard Monday that the victim was stabbed to death at the end of November 2017, but her body was not discovered weeks later.

On Friday, a testimony included the claim that the teen barricaded himself in the home for that time.

The first of the four peers who took to the stand says they saw the teen at a friend’s house around Christmas of 2017.

He said the teen had cuts on his fingers, was complaining about his toes hurting, and had a backpack with toilet paper, change of clothes, and canned foods.

“He said he committed a crime,” the friend said. “We didn’t know what crime he committed. We tried to squeeze it out of him.”

The friends who took to the stand went to school with the teen and had not seen him there for several weeks.

A different friend claimed that, in a video they submitted as evidence, the teen confessed to him at a nearby park.

The friend said, “he walked upstairs and went to his Mom’s bedroom.  He saw her. Her back facing towards him. He said she turned around and charged at him with a knife. He covered himself and deflected.”

In a video statement, the friend said that he think he kicked her, grabbed her hand, took the knife, and jabbed her in the side of the head.

A friend also told police that the teen mentioned he locked himself in the basement for three weeks.

During cross examination of one of the friends, the defence asked if the teen exhibited any violence or if they do drugs or alcohol.

“No,” the friend said. “He usually stays home and plays games.”

The friend said he was told by the teen that he disposed of the knives in a garbage bag that was taken to the landfill.

In a video statement to police, the friend said, “he said he didn’t regret it. He didn’t feel guilty. He said eventually it was going to happen either way.”

The victim’s brother told the court he was concerned when she didn’t respond to calls or texts and was the one who found her body in her home.

The court heard that the teen was arrested days after the body was discovered.

The teen has pleaded guilty to second-degree murder and has his identity protected because he is being tried as a youth.

The crown alleges evidence will suggest he is guilty of first-degree murder and is applying for an order that he be sentenced as an adult.
