A 56-year-old man died at the scene of an accident in Gwynedd, police said.
A vehicle was involved in the incident on the A498 near Llyn Gwynant. Officers were called at 13:00 GMT Sunday.
Police are trying to establish the circumstances of the accident and appealed to witnesses who might have seen the Mazda MX5 money.
They want to hear from anyone who has seen it anywhere between Corwen and Nant Gwynant since Thursday.
It is believed that the vehicle left the road and that it was closed for several hours Sunday, as a result of a police investigation.
