Police are urging a couple who walked past a murder scene in Scarborough just minutes after a man was stabbed to come forward to help with their investigation.
The man and woman were on Foreshore Road, opposite the Olympia amusement arcades, at about 11.35pm on Saturday 13 April.
A 17-year-old boy, who was stabbed in a leg, shouted to the couple for help while he was phoning for an ambulance.
His friend, 19-year-old Michael Vincent Graham, was fatally wounded in the incident.
