Fairweather was referred to a youth offending team after he punched an acquaintance in the head and held up a convenience store with a kitchen knife in January 2014.

An Essex County Council spokesperson said it had carried our a review of the case which found it could not have prevented the killings, the first of which happened just two months later.

“We can confirm that the defendant was known to the Youth Offending Team and was subject to a 12 month referral order. 

During that time he had contact with the Youth Offending Team at least once a week and complied with all actions and appointments required of him. A referral order does not warrant constant supervision," a spokesman added.

Essex University, where Fairweather's second victim Nahid Almanea was studying, said it will continue to honour her memory through the Almanea Scholarship for Science, which is offered to overseas students studying science or health-related subjects at postgraduate level.

Registrar of the University of Essex Bryn Morris said: “Nahid was a bright, talented and conscientious member of our University community. She was a considerate and well-respected student on our Essex English Language Programme and is missed by her teachers and fellow students."

Speaking after James Fairweather was found guilty of the 2014 murders of two strangers, Paul Scothern, of the Crown Prosecution Service, said: "This was a shocking case, particularly because of the young age of the defendant at the time and because the brutal attacks he carried out were entirely random."

Mr Scothern said Fairweather had "absolutely no reason" to attack them, adding: "Our evidence was that he was in control at the time, he knew what he was doing, he prepared for the killings by arming himself with a knife and gloves, and he took steps afterwards to conceal what he had done."

Here is a timeline of the murders...

The investigation was one of the biggest Essex Police has ever undertaken, as revealed by these numbers.

Assistant Chief Constable Steve Worron led over 1,500 police officers as part of the investigation, and said it was a "long and difficult inquiry".

There were extensive forensic searches and officers spoke to hundreds of potential witnesses, reviewed hundreds of hours of CCTV and examined telephone records and social media posts.

Fairweather was "turned on" by serial killers and researched Ian Huntley, Myra Hindley and Yorkshire Ripper Peter Sutcliffe, of whom he had a picture on his phone. The court heard his favourite serial killer was American Ted Bundy, who sexually assaulted, murdered and decapitated his victims. He wanted to emulate the serial killers he idolised and fantasised about killing his headteacher and parents, the jury was told .

After he killed, he obsessively looked up press coverage of the murders on the internet. He spent his days thinking about "killing, raping and watching pornography", the jury of five men and seven women were told.

Essex Police has released this map of the investigation into the Colchester double murders, which Assistant Chief Constable Steve Worron said was "one of the biggest investigations" ever carried out by the force.

Fairweather showed no emotion as the jury delivered its unanimous verdicts after deliberating for eight hours and 33 minutes.

Mr Justice Robin Spencer QC warned the teenager he faced a lengthy prison sentence, adding that the starting point for two murders for someone under 18 is 12 years. 

He also turned and thanked the jurors for their "diligence" in dealing with such a "harrowing" case before excusing them from jury service for four years. 

Police released a video of their interview with James Fairweather, in which he described stabbing his first victim, James Attfield.

He says: "The voices were talking to me: 'You need to make a sacrifice or we're going to come and get you'."

Fairweather's second victim, Nahid Almanea, a 31-year-old student at the University of Essex, was stabbed on the Salary Brook Trail footpath on 17 June as she walked to the Wivenhoe campus from her accommodation in Woodrow Way.

In the month following her death, her family issued a statement saying they has been left "devastated by the terrible murder of Nahid."

"Nahid was a remarkable and gentle person who was loved for her kind and caring nature. Publicly Nahid was a quiet and dignified lady.

"However, when she was with her family Nahid was a warm and loving person who enjoyed laughter and the company of her parents, siblings and extended family. The amount of people that attended Nahid’s funeral is a tribute to how much she was cared for and respected,” the statement said.

Following the verdict, Fairweather was remanded in custody ahead of his sentencing at the Old Bailey next Friday.

Steve Worron, Assistant Chief Constable of Essex Police, said: "Fairweather admitted killing James and Nahid, but denied their murder was calculated and pre-planned.

"He then forced their families to endure the pain and grief of a trial rather than admitting he had murdered them.

"Today's verdict will never heal the pain of losing their loved ones in such horrific circumstances.

"Hopefully they now have some answers and can be reassured their killer will face a long time behind bars."

Fairweather's first victim, James Attfield was found with 102 stab wounds near Castle Park in Colchester, in March 2014.

Speaking after the trial, his mother Julie Finch thanked police and said she hopes the family can begin to move now that "justice has been served."

"At the time we had no idea the killer was so young - a fact that makes my sons' death feel all the more cruel and unnecessary."James Fairweather is a monster in our eyes - and we will never be able to forgive him," she added.

Police found he was carrying a knife (pictured) and initially arrested him on suspicion of possession of an offensive weapon.

They later charged him with the murders of James Attfield, 33, and Nahid Almanea, 31, both of whom he stabbed to death in 2014.

When psychiatrist Dr Simon Hill assessed him last August, Fairweather was describing some of the "most anti-social and violent thoughts" he had come across in his professional practice.

Fairweather claimed to hear voices telling him to set fire to babies, expressed a hatred of prostitutes, saying voices told him to pull out their tongues. He also described how when his head teacher had made him angry, he could not contain his excitement at the idea of harming him and throwing acid in his face.

James Fairweather's early school reports tell of a boy "sensitive to the feelings of others" but later reports showed evidence of violence. 

He was sometimes teased about his ears, was a "bit of a troublemaker" and a "wide-boy" whose attendance became sporadic. Teachers described incidents of kicking, head-butting and tossing school furniture around. But there was little evidence to suggest he would kill, they said.
