A 61-year-old man has died in prison a decade after he was convicted of killing a Good Samaritan in Vancouver's West End.

Corrections officials say Mirhashem Seyed-Fatemi died in hospital Monday of natural causes.

Seyed-Fatemi was 10 years into a minimum 15-year prison term before parole eligibility following his conviction for the second-degree murder of Tony McNaughton.

The manager of a Starbucks coffee house was hailed as a hero after he was stabbed to death in January 2000.

McNaughton died while trying to stop Seyed-Fatemi from attacking his estranged wife, a Starbucks employee, with a butcher knife.

McNaughton was posthumously awarded the Governor General of Canada's Medal of Bravery and the Carnegie Medal for Extraordinary Heroism.
