Supplied by Taylor Ablett. A Timmins teen is pleading guilty to manslaughter nearly two years after 19-year-old Austin Theriault was found dead in Bozzer Park. 19-year-old Nathan Koostachin was facing charges of first degree murder for the death of Theriault back in July 2016. The courts say there was some animosity between the two boys and on July 12th, both Theriault and Koostachin were in Bozzer Park. Court documents say Koostachin led Theriault to a secluded part of the park for a fight that Theriault was not aware of. Both boys had knives on them, but Theriault kept one on hand for safety because he slept in the park on occasion. During the altercation, Koostachin pulled his knife and hit Theriault in the chest. The defense came to an agreement on a plea of manslaughter, meaning there was no intent to murder. The joint submission is recommending a 10-year prison sentence, eligibility for parole in 2021 and a lifetime weapons ban once released.
