PORTLAND, Ore. -

An Oregon teenager who carved a swastika into his ex-friend's forehead during an episode of torture has been sentenced to 11 years in prison.

  In a quiet voice, 16-year-old Blue Kalmbach told the victim in a Portland courtroom Thursday that he was sorry for his actions.

He was the last of four teenagers to be sentenced in the case. Police and prosecutors said the teens had spent the evening before the February attack sketching out ideas for torturing the victim.  Before Kalmbach carved the swastika, they shot the victim with a BB gun, hit with him a bat and forced him to eat cat feces.

The victim did not address the court and bangs covered his forehead. His mother said the scar has mostly healed, but her son has nightmares.
