A teenager who murdered and attempted to decapitate his 12-year-old friend has been jailed for a minimum of 16 years.
Marcel Grzeszcz, 15, stabbed Roberts Buncis "in excess of 70 times" during a "brutal and prolonged attack".
The boy, who was 14 at the time, lured his pal to woodlands before killing him in December last year.
The incident happened near Boston, Lincolnshire, in the UK just two days before the victim's 13th birthday.
A trial heard previously that Grzeszcz "intended at the very least to inflict serious violence" on his young victim because "he was a snitch".
The defendant claimed Buncis had taken the knife to the scene and he "lost control" when the young man attempted to stab him.
However, this theory was not accepted by jurors in the court and they instead concluded Grzeszcz was "motivated by anger and tried to punish the deceased rather than losing self-control".
The teen had admitted manslaughter during his trial and denied murder but was found guilty of the more serious charge in July.
He was sentenced to a minimum of 16 years and 36 days in prison on Monday, reports LincolnshireLive.
Grzeszcz could be not be named until a High Court judge lifted reporting restrictions after he was sentenced.
The judge said of the defendant: "When the two of you met up in the wooded area, I'm satisfied while the deceased was unarmed and unaware of what was to take place, you came armed with a large knife and with latex gloves intending at that time, at the very least, to cause him serious bodily harm."
Buncishad suffered fatal blows to his neck, chest and abdomen, during a "brutal and prolonged attack", it was said previously.
Originally from Latvia, he was being raised by his single father Edgars Buncis, who brought him to the UK to give him a better life.
Brendan Kelly QC, defending, said that based on the evidence the defence conceded that at some point the intention to kill was formed, as the Mirror reports.
"There was at least some evidence that what happened was not the entire plan, that what happened went wrong," he told the court.
Mr Kelly described Grzeszcz as a troubled young man who suffered a period of chaos that was missed by his parents and the authorities.
In a victim impact statement read to Lincoln crown court during the sentencing hearing, Buncis' dad said that "no father should ever have to bury his son".
"I have lost my destination, my purpose," Mr Buncis said.
"My life is in the cemetery. I feel empty, nothing will change this."
