Watch moment killer tries to hide knife in pocket after stabbing man in the back
A knifeman who stabbed two men in separate incidents - killing one of them - has been jailed for life.
CCTV footage released by Humberside Police shows the moment Callum Strachan tries to conceal a knife he had used to stab a man in the back in Grimsby as part of a jealous feud.
Remarkably, while being investigated for the attack on the man who he stabbed multiple times on June 15, 2024, Strachan then attacked another man with a blade in Monk Bretton in Barnsley, stabbing him to death weeks later on September 1, 2024.
Alan Sutton, a father-of-two, died at the scene from a single stab wound to the chest.
CCTV footage discovered by South Yorkshire Police showed Strachan sitting on a wall as a marked police vehicle travelled towards the scene, attempting to hide the fact that he had just left the area.
When he was arrested on suspicion of GBH, he claimed it was others who attacked Mr Sutton. But he was arrested on suspicion of murder when the 41-year-old was later pronounced dead.
Now 23, Strachan was sentenced to life in prison with a minimum of 24 years at Sheffield Crown Court on Friday (May 1).
Strachan, of Burton Road, Barnsley, admitted seven offences including murder, possession of a bladed article in public, and two counts of threatening with a bladed article.
Mr Sutton’s family shared a touching tribute in which they said he was “so much more than a victim in a court room”.


It said: “Alan will never get to see his daughter grow up, he will never see any of her milestones, walk her down the aisle when she gets married, or meet her future children. Alan will never get to meet his sons’ adorable baby, his first grandchild.
"After a long wait to get this trial to court, which has had a big impact on his whole family, both mentally and emotionally, we are relieved that justice has been served. No sentence will ever truly compensate for the loss of Alan and the pain that we all feel.
"Alan was so much more than a victim in a court room, he was a devoted parent and an amazing partner to myself. He was a well-liked, caring person and much loved within our community.
"He had a heart of gold and he will be truly, truly missed."


Detective Chief Inspector Ben Wood, who was the senior investigating officer on the murder case for South Yorkshire Police, said: "Strachan thought he could get away with his deplorable actions, fleeing from the scene and stating he was a victim when officers arrested him.
"Clear CCTV and dashcam footage has proven to a jury that he was involved and was the one responsible for taking the life of Alan.
"I hope the results handed out today bring Alan's family some justice they deserve."
Police Constable Dan Greaves, from Humberside Police, said: “This was a completely unnecessary and brutal attack on a defenceless man leaving him for dead in the street all over a jealous feud.
“I would like to commend the victim for coming forward and supporting the investigation; the events of that night have greatly affected him both mentally and physically, and whilst I am pleased Strachan will now be spending ample time behind bars, this result will not take away the fact the victim must live with those scars for the rest of his life.
“The detrimental impact that one knife can have on so many lives is devastating, and the victim in this case is extremely lucky to be alive.”
