Thomas Farr, 31, died from multiple injuries after he was hit by a car on the A22 Caterham bypass, at about 23:00 GMT on 26 March.
Police said his death may be linked to an "altercation" at a flat in Croydon Road, when another man was stabbed.
An inquest into Mr Farr's death has been opened and adjourned.
A pedestrian who was killed in a collision that police believe may be linked to an earlier disturbance at a flat in Surrey has been identified.
