A teenager who died at Hillsborough tried to swap his terrace ticket for a place in the stands in the hours before kick-off, a court heard.
Paul Carlile, who was 19 and an apprentice plasterer, was among the 96 Liverpool supporters who died in the tragedy at the 1989 FA Cup semi-final.
The new inquests heard Paul had gone to the match with friends and had gone to a pub before the game in an attempt to swap his standing ticket for a seated one.
Footage was shown to the court of Paul on the terraces in the minutes before the 3pm kick-off.
Richard Goulding, who was a detective constable with South Yorkshire Police at the time, said he saw Paul being laid outside Gate C by the ground and attempted to revive him with the help of another policeman and an ambulanceman.
He said: “However at this time he was not breathing and showing signs of purple discolouration around his face.
“After several minutes of resuscitation, he showed no signs of recovery and it was not possible to find a pulse. He was obviously dead.”
Mr Goulding said he thinks he covered Paul with his coat after a decision was made to stop resuscitation.
He said he remained with Paul throughout until they were moved by ambulance to the stadium gymnasium and was present when he was confirmed dead by a doctor at 4.35pm.
Paul’s body was identified the following morning by his uncle at the Medico-Legal Centre in Sheffield.
The inquests continue.
