24 Hours will broadcast horrifying details of the manhunt sparked by Rob Parkins stabbing Alex Fitzpatrick to death.
The Channel 4 documentary recounts how Alex, 30, was knifed 17 times in the neck and chest in 2019.
The “brutal” attack came just moments after he had dropped his son back home in St Neots, Cambridgeshire.

Alex returned to the house after realising the child had forgotten his glasses.
However, a row erupted – and Alex died at the scene.
Why did police interview Rob Parkins’ mother?
Parkins fled St Neots to hide at his aunt’s house in north London, leading to a police manhunt.
Parkins’ mother Janet and father were both arrested on suspicion of assisting an offender but later released without charge.
The episode also includes her interview with police.
She says at one point: “I would feel that any loving mother would protect her children and try to help her children.”
What was Rob Parkins’ sentence?
Parkins claimed during his trial he was “not aware” he was holding a knife during the row.
Nonetheless, he was found guilty of murder. Jurors took only two and a half hours to consider their verdict.
He received a sentence of life with a minimum of 19 years in August 2020 for causing “horrendous and unsurvivable injuries” to Alex.
How did police react to the sentencing?
Detective Superintendent Michael Branston led the investigation.
He said: “This was a brutal, frenzied and sustained attack resulting in the death of a man whose son will now grow up without his father in his life.
“What started out as a dispute escalated to such a degree that Alex lost his life from misuse of a knife.”
