Police want to speak to any of the passengers pictured in the video.
Mr Cookson was last seen alive at the junction of Hillcrest Road and Welford Road in Wigston, Leicester.
Two men, aged 20 and 24, and a 49-year-old woman have been arrested on suspicion of manslaughter and released on police bail pending further enquiries.
Det Insp Simon Shuttleworth said: "I am keen to stress that none of the people in this footage have done anything wrong and are in no way under suspicion.
