A killer who stabbed his prospective mother-in-law in Birmingham more than 60 times in a pre-planned murder was jailed for at least 27 years.
Robert Edwards, of Tipton, who launched the brutal knife attack just four days after his fiancee called off their wedding, refused to enter the dock for his sentencing at Birmingham Crown Court.
The 43-year-old delivery driver was found guilty of the murder of Sylvia Smith on Tuesday following a two-week trial at which he denied any involvement in her death.
The trial heard that Edwards, of Monins Avenue, Tipton, launched the attack on the 59-year-old at her home in Erdington, Birmingham, after his relationship with her daughter broke down.
Jailing Edwards for life and ordering him to serve at least 27 years before being considered for parole, Mr Justice Supperstone described the murder as "planned and premeditated".
During the trial, jurors heard that Edwards also punched and stamped on Mrs Smith on May 7, causing severe injuries to her head and face.
Edwards was unanimously convicted after jurors heard how Mrs Smith, a part-time home help, was left to die in a pool of blood at her home in Mere Road.
The opening of the trial heard that Mrs Smith's daughter, Samantha Smith, had been in a long-term relationship with Edwards since 2000, when they met while working at Birmingham's Longbridge car plant.
But the relationship eventually broke down and Miss Smith, 36, left Edwards in April to move back to her mother's home.
The court heard that she later cancelled their wedding, which had been planned for August, after Edwards threatened to commit suicide.
