Calgary Teen Sentenced For Sexual Assault Against Younger Foster Brother


CALGARY -- A 14-year-old boy who was found guilty of sexually assaulting his young foster brother has been sentenced.

The defence and Crown asked for a six-month sentence to be served in the community followed by 18 months probation, which a Youth Court judge agreed with.

As a result, the mentally challenged teen will be placed in a group with the aim of giving him supervision and guidance.

The boy was 12 when the assaults first began against the three-year-old and continued for about a year before he was arrested after a neighbour witnessed an assault and called police.

Det. Stephen Johnston of the Calgary police child abuse unit says it was "a very diifficult case right from the beginning, and very disturbing circumstances.''

He says it's nice that the Crown, defence and judge "all came together'' to understand the context of the case.

Court heard the 14-year-old functions at the level of a four or five-year-old and has permanent brain damage, as well as attention-deficit-hyperactivity disorder and fetal alcohol syndrome.

When asked about his crime, the teen told the judge: "I just feel bad, it won't happen again.''

"We have a child that's offended in a horrifying way against another child, but coming out of that there's a path to hopefully getting this offending child the help he needsaand to maybe have a better life ahead of him,'' Johnston said.

Psychiatric assessments found the teen needs constant supervision, and could be a risk to reoffend.
