BRIGHTON MAN JAILED FOR STABBING GRANDMOTHER TO DEATH
A 19-year-old man who stabbed his grandmother to death has been jailed for 15 years.Pietro Addis admitted attacking Sue Addis at her home in Withdean, East Sussex, in January 2021, but claimed diminished responsibility.
A jury at Lewes Crown Court accepted his defence and found him not guilty of murder.
He had previously pleaded guilty to manslaughter.
Addis had been living with his grandmother, but fell out with her over his use of cannabis, the court heard.
He was on medication after being diagnosed with Attention Deficit Hyperactivity Disorder (ADHD) in 2018.
At the time of the attack, Ms.
Addis had been investigating how to get professional help for him.
Addis will serve at least 10 years in jail, and five years on license if granted parole.
His trial heard he had made a 999 call on the day of his grandmother's death.
Police found Ms.
Addis in the bath.
She had been stabbed 17 times.
Judge Christine Laing KC said while the jury had accepted a plea of manslaughter due to diminished responsibility during a 'psychotic episode,' Addis retained a high degree of responsibility for the crime.
Detective Superintendent Mark Chapman said: 'This is a tragic case in which a much-loved grandmother, who was widely respected in the Brighton and Hove community, has lost her life in the most terrible circumstances.
Our thoughts remain with the Addis family and loved ones who have behaved with dignity and compassion throughout this harrowing ordeal.'
