A man has been jailed for life for stabbing a stranger to death in an unprovoked attack in a playground in Crawley.
Vladimir Ivanov stabbed 61-year-old Glyn Rouse in November 2017.
Ivanov attacked Mr Rouse with a kitchen knife in broad daylight.
Mr Rouse was found by passers-by with serious wounds on a footpath near a playground on Cherry Lane.
He died at the scene.
Ivanov told officers that he took a knife from his home as he went jogging on Cherry Lane that morning.
Mr Rouse and Ivanov were complete strangers to each other, and the pair had no interaction before he attack him.
The 23-year-old told police that "something in my mind told me to do this".
Ivanov pleaded guilty to manslaughter on the grounds of diminished responsibility.
He was sentenced to life in prison with a minimum term of 4 years, as well as being detained indefinitely under the Mental Health Act.
