As horrible stories go, what you related seems even more serious—because this is another one—than what happened to the young Sébastien Lacasse. The killer in that case was a juvenile, and the other participants in the assault were over 18. The heaviest sentences were four years, and the young person who killed him was sent to an adult prison and was condemned to life in prison.
With regard to the young people you were talking about, would you normally expect that this is what would happen, that is to say that they would be referred to an adult court?
