They can't be rehabilitated.
Christian Philip Oberender, then 14 years old, had murdered his mother in a shotgun ambush in the family rec room in 1995.
Now, 18 years later, he writes a letter. His Facebook page showed firearms spread out like a child's trophies on a bed inside the home, along with notes about the Newtown, Conn., gunman who shot 20 children to death.
Even more disturbing was the letter Oberender had written recently to his late mother, Mary: "I am so homicide,' it said in broken sentences. "I think about killing all the time. The monster want out. He only been out one time and someone die.'
"I think about killing all the time,' Oberender wrote. "Why god do I feel like this? The monster want to hurt people. Guns are too fast. The monster want it to be slow and painful. There is so much pain in my heart and soul. Me want other to feel it."
Oberender had been working as a skilled mechanic at a local sanitation hauling company.
