Looking through a family photo album with his mum, three-year-old Ashton Barrett points to one of the pictures - 'That's my mummy and daddy', he said.
'My daddy is in heaven.'
Ashton is a confident and chatty little boy, but he is growing up without his father.
Yesterday his father's killers Jesse Quaye, 18, and 15 year-old Ayomindy Bile, who can now be named after Judge Stephen Holt lifted reporting restrictions, were both sentenced to a minimum term of 15 years in custody after they were convicted of murder following a trial in November last year.
Mr Barrett, 20, of Abyssinia Close, Great Yarmouth, died as a result of a fatal stab wound following a 'joint attack' at a 21st birthday party on May 10, last year.
Sentencing Quaye and Bile at Norwich Crown Court, Judge Holt said: 'This is a deeply tragic case. There are no winners. A decent and loving young man has had his life taken leaving his family and friends devastated and a young son's life decimated.'
'The one message that must go out is young men who carry knives they won't be able to pull them out and use them. If you use a knife and kill you will spend a long time in prison - even if you are a boy.'
He described Mr Barrett as 'a thoroughly decent young man who had just taken on the responsibility of fatherhood' but added his words would be of 'little comfort' to Mr Barrett's family and friends who will 'have to live with the loss for the rest of their lives'.
He said Mr Barrett's son Ashton would have to 'grow up never knowing your father'.
At home with his mother Kayleigh Simpson in Yarmouth, Ashton is full of energy and eager to play. But Miss Simpson knows that what last summer will shape the person her son becomes.
Speaking ahead of yesterday's sentencing his family said it was hard to put into words how much their lives had changed but the 20-year-old would never be forgotten.
'It feels like the horrible part is finally over and we can start remembering Connor for who he was,' said his father, Lee Barrett.
'And having Ashton is like having a light in our lives.'
Mr Barrett, Miss Simpson and many of Connor's friends attended the sentencing yesterday. Miss Simpson missed only three days of the trial at Norwich Crown Court last year.
'Yeah, it was hard to hear but I needed to,' she said.
'The first couple of days were the most difficult: seeing them in the dock but after that, I guess I got tougher and I heard what happened over and over again.
'I never thought anything like this could happen to us, but it has and now I have to live with the fact that Ashton does not have a dad.
'He knows his daddy's not here anymore. But I am going to have to tell him what happened when he's old enough to understand. I'll probably have to tell him again and again as grows up, goes through school and other people ask where his dad is.'
Miss Simpson and Connor had known each other since childhood and were together for four years, separating just a few months before Connor was killed.
'We weren't together but he was like a best friend,' she said.
'He was the most devoted dad. He would help out every day, anytime I asked. He loved him. Ashton is the last thing that's left of Connor.'
Connor's own father moved from London to Norfolk in the 1980s.
'We came from a bad part of the East End - there was violence but we're talking about punch ups not knife crime.'
Before his son's violent death last May, Mr Barrett paid little attention to reports of youth gangs or youngsters carrying weapons.
With the court hearings over and the boys who killed Connor now behind bars, Mr Barrett said he can focus on moving forward.
'I will never, ever forget Connor,' he said. 'I don't want to. But now we can remember the happier times.'
Teenager killer was on bail at time of murder
One of the teenagers who killed a 20-year-old following a fatal knife attack at a Hemsby party was on bail at the time after he was arrested for being in possession of a kitchen knife less than a month before the murder, a court has heard.
Ayomindy Bile, 15, of Howard Street, Great Yarmouth, and Jesse Quaye, 18, of College Court, Crittens Road, Yarmouth, were both sentenced to 15 years in custody at Norwich Crown Court yesterday after a jury found them both guilty in November of the murder of Connor Barrett last May.
The teens, who were also convicted of causing actual bodily harm to another man Ricky Halliday, who was another guest at the party, were described as being 'heavily into a knife carrying culture' by Judge Stephen Holt.
The court heard that at the time of the murder Bile, who pleaded guilty to possessing offensive weapons at the start of the trial, was on bail after being arrested for being in possession of an offensive weapon just a month before in Great Yarmouth.
Quaye, who was found guilty of possessing offensive weapons, had one reprimand for threatening behaviour.
Amjad Malik QC, prosecuting, said the case highlighted how serious the use of knives 'routinely' by young people in our society can be 'for the purpose of aggressive violence'.
Also sentenced yesterday was a third defendant, Anthony McLean,41, of Gatacre Road, Great Yarmouth, who was found guilty of assisting Quaye to evade justice by driving him to London in the hours after the attack.
McLean was jailed for four and a half years.
Stephen Spence QC mitigating for Bile, said it was not 'pre-planned' but a 'moment of madness'.
Paul Keleher QC, for Quaye, said there was a lack of intention to kill, a lack of premeditation and a degree of provocation.
Lori Tucker, for McLean, said her client was at the time of an offence an alcoholic and is being treated for depression.
She said Quaye was a friend of his son's who he himself treated like a son.
Youth knife crime in Norfolk
Fatal attacks, like the one at a 21st birthday party in Hemsby in May last year during which 20-year old Connor Barrett lost his life, are thankfully few and far between in Norfolk.
But it is perhaps surprising they are not more frequent judging by figures released by police about the number of incidents they are called to involving youths with knives.
Over the past three years officers have been called to more than 160 incidents in the county where people aged 18 or under have had knives.
Children as young as 10 have been involved in some of the 163 incidents police have released details of following a Freedom of Information request.
Figures show that in 2011 to 2012 there was a total of 38 people aged 18 or under charged with offences, including one 11 year old and three 13 year olds, ranging from burglary and robbery to murder.
In 2012 to 13 there was 32 young people charged with knife crimes, including two 13 year olds and four 15 year olds, while between 2013 and 2014 there was 24 young people charged, including two 12 year olds.
But Sergeant Tim Horrobin from the force's Safer Schools Partnership, said: 'Knife crime in Norfolk is not a huge problem. We do have a small number of violent incidents but a lot of it is about kudos and bragging among peer groups.'
Kate Biles, from Victim Support Norfolk, said while the number of incidents in the county was 'not particularly high' it was 'worrying' there were any.
She said: 'Knife crime is particularly frightening because it can so easily cause serious injury or even death.'
