A teen was given a lengthy prison sentence for murder after he admitted to the horrific crime.
Joshua Delbono, from the United Kingdom, received a life sentence after he stabbed 16-year-old schoolboy Charley Bates during a fight between two groups in Somerset last summer.
Delbono, then 18, came home approximately six hours later and told his mom about the incident which resulted in her calling the police on her son.
The chilling emergency call became a focal point during a two-week trial at Bristol Crown Court where the jury found the defendant guilty, thus sentencing him to life in prison with a minimum term of 21 years.
As per the Daily Mail, the court heard Donna Delbono speaking to the operator that night after her son returned to their home in Frome, eight miles away from Radstock where the murder took place.
"My son's killed someone," the concerned mom told emergency personnel.
When asked for the location of the incident, she said: "It was at Radstock earlier. He's just come back and I've found out. He's in my house now but I can't let him go anywhere."
"I've told him I've got to do it," she added.
She then handed the phone to her son, who said: "I don't know anything about him [the victim] at all. I went in to help my mate. I thought 'I'm not getting stabbed.'"
The court also heard details of the incident prior to the murder taking place.
It was said that two cars arrived at a parking lot, one of which contained Delbono, and the other with Bates. The 16-year-old approached the car because of a dispute with one of the defendant's friends over some money and immediately a fight broke out between the two which also led to their friends getting involved.
Delbono then picked up his weapon and proceeded to stab the victim in the chest, also injuring his arm in the process as the teenager tried to defend himself.
The perpetrator and his group fled the scene before emergency services arrived. Unfortunately, Bates was declared dead at the scene just half an hour later.
It was later alleged that Delbono then travelled to Shearwater Lake where he was pictured burning his clothes. However, when he returned home just a few hours later, his mom called the police.
The prosecutor, Adam Vaitilingam KC stated: "His girlfriend thought it was a good idea to film this, and photos were recovered from her phone by the police."
He continued: "It started as a one on one fist fight but eventually it escalated. The passenger got out and so did one or two of Charley's friends However, at that stage, the defendant was not involved and was sitting in his car.
"But at some point in the fight, the defendant got out of the second car, had a knife, walked over to where the fight was happening and stabbed Charley several times, including in the chest," Vaitilingam added.
Judge William Hart said that what started out as a normal fight between two groups ended with a "young boy with his whole life ahead" of him lying dead on the ground.
"You took the knife from the car intending to use it as you did, not to warn people off," he told Delbono.
Judge Hart added: "Let me say to all who hear my remarks of the damage that is caused by carrying knives. You may rob a person of their life. What happened that day cast a horrible shadow over everyone."
Delbono was found unanimously guilty by the jury and is set to serve a life sentence with a minimum of 21 years.
