A UK judge has sentenced a 17-year-old boy to one year in prison for the "sadistic" torture and killing of two kittens. The teenager had also expressed a desire to kill a human and researched how to "get away with murder."

• Two kittens were found mutilated in a London park in May, with evidence of burning and knives, blowtorches, and scissors at the scene.
• The boy, who cannot be named for legal reasons, pleaded guilty to possessing a knife and causing unnecessary suffering to animals; a 17-year-old girl is also facing sentencing.
• Notes on the boy's phone revealed, "I really wanted to murder someone. Every day I was researching how to get away with murder," and "I have killed cats to reduce my urges."
