A young man who killed a stranger after hearing voices in his head has been jailed for life.
Vladimir Ivanov stabbed Glyn Rouse so hard in the neck, head, chest and arm that he broke the kitchen knife handle.
The 23-year-old left his victim dying in the street in Crawley, West Sussex, and despite efforts from emergency services, he was pronounced dead shortly after the attack on November 28, 2017.
DCI Mike Ashcroft said: “Mr Rouse had been out walking and minding his own business that morning when he was subjected to an unbelievable, highly unusual, unprovoked attack.
“Ivanov’s motive for killing an innocent man remains unknown, but it appears to be bourne from his mental state at that time.”
Bulgarian Ivanov, a warehouse worker who lived in Crawley, was arrested in the area shortly afterwards, covered in the 61-year-old victim's blood.
During police interviews, he told officers he took a knife from his home and put it in his jacket pocket as he went jogging that morning, because "something in my mind told me to do this".
Ivanov was found guilty of manslaughter on the grounds of diminished responsibility and sentenced to life imprisonment.
Mr Rouse's family described him as "extremely talented man" who "brightened" people's live with his guitar playing and artwork.
Their spokesperson added: "Glyn was dedicated to his art and spent a lot of time carrying out this hobby, his amazing talent at art shines through when you look at his numerous paintings and sketches, and it was obvious that he was a very talented, precise and expressive person.”
