Modig, who has said he was asleep when the car crashed and who was not able to explain how the vehicle swerved off the road, said his mind remained blank and that he still doesn't have any recollections of the incident.
"No, I don't. I'm sleeping when the crash occurs so I go from a sleeping state into being unconscious for about half an hour. I wake up in the ambulance."
Ofelia Acevedo, Paya's widow, has said she does not believe the Cuban government investigators' account of the accident, saying she hoped Carromero would be able to tell the truth once on Spanish soil.
