Hull Jason Kowalski stabbing: Man found guilty of murder
A man who stabbed a "kind and caring" man to death outside a property in Hull has been found guilty of murder.
Jason Kowalski, 39, was found injured outside flats on Westbourne Avenue on the morning of 15 February. He later died in hospital.
Louis Fowler, 21, denied murder but was convicted by a majority verdict of 10-2 following a trial at Hull Crown Court.
Police said Mr Kowalski was killed while "bravely trying to protect himself and his friend".
He was stabbed through the heart after an argument over an alarm, detectives said.
Mr Kowalski had been visiting his friend who lived in the flat below Fowler, before the killer confronted the pair to complain about an alarm that went off, according to the Hull Daily Mail.
Det Ch Insp Wendy North, of Humberside Police, said: "This was a tragic loss of life arising from an argument over an alarm which escalated out of all proportion.
"Jason Kowalski could not have anticipated that Louis Fowler would have continued the argument by returning with a knife.
"Our thoughts are with Jason's family as they now try to come to terms with their loss."
Fowler, of Westbourne Avenue, is due to be sentenced on Friday.
In a statement, Mr Kowalski's family previously said: "Jason was well-loved and will be missed by his family and friends.
"He spent his life looking out for other people and was a kind, caring man.
"He had been a truck driver until his recent illness and had spent some time in Zimbabwe as a young man building an orphanage as part of a Raleigh International programme.
"He leaves behind his mum, a twin sister and two young nephews."
