For goodness sake people,a 9 years old CHILD does not normally steal, do drugs, know about sex or whatever. What the heck have the parents doing or not doing to this child. This is not normal. This was learned conduct. Either at home or in a environment.
As to the boy of 8. The Dad raised him. Who knows what went on behind closed doors, what the boy was taught and raised from a young age.
When you have children who are "not normal" and commit crimes at a "tender" age, I look to what they have been allowed to do, what the home environment was like, abuse, substance abuse, what was said in the home.
Children are not born knowing how to kill and handle guns and do drugs. It is learned and learned most likely at home.
The damage needs to unlearned and undone.
In Canada, no one under the age of 12 can be charged with a crime. Any crime, but then again, we have strict gun control laws. Very strict, that prevents a child from access to a gun, handling a gun, or possession of a gun.
