Christopher Cook, 44, admitted murdering Jacqueline Kerr, 54, earlier this year in a callous attack at her flat in Sunnyside Road, Aberdeen.
Aberdeen High Court was told he launched a frenzied assault on January 16 which left her with numerous serious injuries. She was pronounced dead at the scene.
Christopher Cook was arrested in connection with her death later the same day and has pleaded guilty yesterday.
Ms Kerr’s family released a moving statement via Police Scotland after Cook’s conviction:.
They said: “Jaqueline was the light of our lives. She was so loved by all those who had the pleasure of knowing her.
“The day our sister’s life was taken was the day part of our lives were taken too. We will never truly heal from the pain.
“We have young grandkids asking where their aunt is. Those who Jacqueline worked with and supported, unable to understand why she no longer comes to work.”
The statement continued: “We wouldn’t wish this on anybody.
“Thank you to all those involved in the investigation.
“Please respect our privacy at this time and allow us to grieve and heal as a family.”
Detective Inspector James Callander, of Police Scotland’s Major Investigations Team, said: “Jacqueline Kerr was subjected to a brutal attack in her own home by Christopher Cook.
“He has now admitted responsibility for his violent behaviour, which resulted in the death of Jacqueline.
“While it cannot change what happened, I hope this outcome in court leads to some closure for Jacqueline’s family.”
Cook will be sentenced on November 3.
