These are the kind of cases that make us Europeans say: "only in America".
Both cases make you wonder what is the matter with kids these days and more speciifically: what's up with their parents? Can't they see they are raising little psychopaths? Looking at the gruwesome details of these cases you start wondering is this can happen just because of all the violence on TV, movies and in games etc..? Is it because society shows people that violence is acceptable to solve problems?
Prosecutors say Gregory and Sarah Kolb, 18, killed Reynolds in Kolb's car at a fast-food restaurant on January 21, 2005, then took the body to Kolb's grandparents' farm and burned it. The pair returned two days later with a third teen and sawed the body into pieces, dumping some remains on the farm and burying the rest in a state park, according to prosecutors. Prosecutors said Kolb was angry because Reynolds, who had recently moved to the state, was taking her friends and had shown interest in Kolb's boyfriend and Gregory.
That is just incredible. But how about that 12-year old:
(...)A jury convicted Evan Savoie, now 15, of first-degree murder for the 2003 stabbing death of 13-year-old Craig Sorger, who was developmentally disabled. (...) The prosecution said the victim had been beaten and had 34 stab wounds. (...) Prosecutors alleged Savoie had planned the killing. They told jurors he had blood on his clothes, access to knives, and lied to investigators, at one point deliberately leading searchers away from Sorger's body but later admitting that.
The Judge, obviously with a great sense of understatment also said:
"Somebody is going to have to figure out how a 12-year-old can be so violent so young."
