Overview
- Portsmouth Crown Court sentenced 68-year-old Martin Suter on 21 November 2025 to life imprisonment with a minimum term of 27 years and 230 days.
- Prosecutors said he armed himself with a kitchen knife, waited at Crofton Cemetery for more than five hours, and attacked Ann Blackwood as she approached their son's grave.
- After the knife blade broke, he used the scissors she had brought to trim flowers, with the court hearing she suffered 19 stab wounds to her neck and shoulder.
- Suter called 999 from the scene to confess and told police he blamed his ex-wife for their son's death.
- He pleaded guilty to murder on the first day of trial after a manslaughter plea was rejected, and the life term also incorporates a separate indecent-assault conviction.
