This is the spine-chilling footage which led to the conviction of a man who murdered the mother of his child more than a decade ago.
Darren Osment, 41, killed Claire Holland, 32, in a drunken row in 2012 before dismembering her body and and dumping her remains in the River Avon, a court heard.
Claire, who also had three children by a previous partner, was last seen leaving a pub in her hometown of Bristol on June 6 of that year but never made it back to her flat.
Her body was never found despite extensive investigations so she remained a missing persons case for years.
The lack of forensic evidence prompted police to launch an undercover operation which saw an officer posing as a petty criminal befriend Osment over a 20-month period.
Covert recordings captured a series of confessions by the 41-year-old pub chef during that time.
In one, he tells the officer: ‘Like I said, I’m not going to go into any details, I did what I did, I did what I done and…’
‘It makes me feel sick. But I did it for (my child). Cause she harmed my f****** child. And how they were brought up is f****** wrong.’
He also boasts of his ‘knife skills’ and runs his hand across his torso while making a swishing sound.
Asked whether Claire’s body would float, he says :’It’s all f*****g weighed, it’s all down, it’s not going to come floating back up.’
Jurors were told Osment and Claire, who were both alcoholics, met in 2008 while working together in a cafe and had a baby in 2010.
The child was placed in foster care after repeated allegations of alcohol-fuelled domestic violence.
In another recording, Osment is heard to say: ‘Yeah because of what she did, f****** c*** mate, f*** her.
‘End of, f*** em, she ain’t going to be seeing the light of day again, don’t worry about that.’
Police reopened a criminal investigation in 2019 after Osment, who was now living in Devon, dialled 999 and admitted to killing Claire.
The undercover officer moved into a flat down the road from the killer’s home in 2020 and portrayed himself as having links to organised crime.
The pair spent hours together playing pool or snooker, going for walks and committing ‘crimes’ staged by detectives to help them bond.
They reportedly got so close that Osment vowed to make the officer, who used the fake name Paddy O’Hara, his best man if he ever got married.
The officer also repeatedly witnessed Osment violently losing his temper, particularly when drinking, jurors heard.
Andrew Langdon KC, prosecuting, said: ‘That is relevant because we suggest that when he met with Claire Holland that night, he is likely to have lost his temper, lost control of himself and in using unrestrained violence he killed her.
‘In other words, he is a man with an explosive temper with a propensity to use violence when angry, including to those who are weaker and more vulnerable than he.’
The jury also heard evidence the 41-year-old confessed to five other people including another ex, her brother, a friend and a prison inmate.
Mr Langdon said Osment had been ‘carrying the burden of knowing what he did to her’ and was seeking to ‘relieve himself of the burden’.
He said: ‘He has, we suggest, never forgotten what he did to Claire.
‘He has always been haunted by the memory of it and that weight, the trauma of that memory, has taken a considerable toll upon him.’
Osment’s ‘heinous’ murder and ‘web of deceit’ brought ‘over a decade of pain’ to Claire’s family, the CPS added.
He was found guilty of murder on a majority 10-2 verdict last Monday and is due to be sentenced on Wednesday at Britsol Crown Court.
