A man has been sentenced to life imprisonment for the murder of a mother-of-two.
Alcwyn Thomas, 44, strangled 45-year-old Victoria Thomas to death at their shared home on Caerphilly Road, Birchgrove, Cardiff, after a day of heavy drinking and cocaine use.
He admitted to manslaughter, claiming her death was a 'sex act gone wrong' during 'erotic asphyxiation.'
However, he denied murder, but was found guilty after a trial at Cardiff Crown Court.
He must serve a minimum of 20 years.
CCTV footage from August 19, 2024, showed the couple visiting The New Inn and Club 3000 Bingo with Thomas' family.
His mood was described as 'argumentative and moody' after consuming 16 pints of lager and taking cocaine.
Further CCTV footage captured him taking cocaine and arguing with Victoria outside the bingo hall before they took a taxi home.
Ms Thomas was last seen alive at 9.26pm when the couple returned home.
Just after 11pm, Thomas sent texts to his sisters saying: "Sorry I done something so bad."
The victim's body was discovered in the early hours of August 20 after his niece, concerned by the texts, went to check on her welfare.
Thomas was found asleep in their bedroom and later admitted to intentionally strangling her.
Detective Chief Inspector Matt Powell said: "Victoria Thomas was a much-loved daughter, mother, sister, aunt, and niece.
"Her devastated family have shown tremendous patience and dignity during this heart-breaking ordeal.
"Our thoughts are with them today as they have been throughout.
"Alcwyn Thomas has shown no remorse and maintained that Victoria’s death was some kind of sex act gone wrong.
"He made no effort to revive her or seek help for her and having killed her he went to sleep in their bedroom.
"He now has to face up to the reality of what he did and spend a very long time in prison."
Ms Thomas' family expressed gratitude for the justice served and the support from South Wales Police, Victim Support, and the CPS.
They said: "We will never get Vicki back... but knowing that her murderer will not live the rest of his days in freedom provides some level of comfort."
