A man has been jailed for life in the UK for murdering his wife, with voice recordings from an Alexa device helping to bring him to justice.
Daniel White (36) kicked in the locked bedroom door of Angie White (45) before he murdered her in October last year.
White fled their home in Swansea, Wales driving his wife's car in the early hours of the morning, before he phoned the police hours later to confess to murder.
Officers discovered the front door unlocked and found the body of Mrs White in her bedroom.
The court heard that White had a long history of domestic violence.
Mrs White had recently installed a mortice lock on her bedroom door, which was kicked in by White after an argument began on WhatsApp.
Neighbours said they heard banging, shouting and screaming at about 3am on that morning, before they heard a front door close and a car drive away.
Shortly before 6am, White called the police telling them: "She's dead. We argued and she locked the door and said she wanted me out".
He went on to describe elements of the murder and how he fled the scene.
Detectives discovered voice commands made by White and his wife stored in the cloud of an Amazon Alexa device.
The court heard that the last message exchanged between Mrs White and her husband was at 3.11am.
A pathologist found Mrs White died from knife wounds to her neck, but noted that there was also evidence she had been strangled.
White had admitted murder but refused to attend court to be sentenced.
Judge Paul Thomas imposed a life sentence with a minimum term of 20 years and 10 months, branding White a "serious danger to women."
After the sentencing, Angie White's family paid tribute to her.
"Angie was a much-loved daughter, sister, mother, grandmother, and auntie. Also, a friend with a zest for fun, always wanting to do whatever she could for anyone and everyone," they said.
"At the time of her death Angie was nearing the completion of her degree in Humanities, a degree which would have enabled her to continue to help others.
"Nothing can bring our beloved Angie back. We shall miss that silly giggle for evermore," they added.
