A chilling video has emerged of a gap year student introducing himself shortly before he died from taking a powerful hallucinogenic drug during a ritual in South America.
Henry Miller, a 19-year-old from Bristol, was in a remote rainforest area of Colombia with other tourists when he took the yage drug with a local tribe.
Miller, who was due to go to university in September, is understood to have died shortly after taking the plant infusion, which brings on vivid hallucinations and supposedly spiritual experiences.
Now, a video has emerged on South American news channels of the student introducing himself and saying it is his second ceremony.
In a statement to the Bristol Post, Mr Miller said: "In the last 48 hours we received the exceptionally sad news that our son Henry has died whilst travelling in Colombia.
"We are being informed of the circumstances through the Foreign Office. He was in the remote Putumayo region.
"We understand that he took part in a local tribal ritual recommended by the hostel that he was staying at.
"The ritual involves a drink made from local plant infusions.
"We are awaiting further information from the Foreign Office but it is likely that a reaction to this drink was the cause."
A fellow traveller said Miller drank a cup of the drug twice, on Sunday and Tuesday, while on land belonging to a local shaman in the remote town of Mocoa in the Putumayo region.
The friend, who asked not to be named, said the drug had no effect on Miller the first time but on the second occasion he became very ill.
He said the group of about eight people, including Miller, were all sick after drinking the drug, a normal reaction to its unpleasant taste.
But while the rest of the group came around from the "trip'', Miller did not.
The friend told the Daily Mail: "He just got worse and worse. He was lying face down on the ground making very weird breathing noises. We picked him up and put him in a chair.
"He wasn't speaking, he was lashing out with his hands and feet. Then he started making weird animal noises, pig sounds and at one point he tried to fly.
"He kept saying, 'What's going on, oh my God' and holding his face.''
The shaman's family told the tourists they would look after him but when they woke up in the morning Miller was not there.
Police arrived and showed them a picture of Miller's body, which was reported to have been dumped by a dirt road.
The friend said police told them he had a crack on his head and that they thought he may have fallen or been thrown from a motorbike.
He said: "Henry was a complete innocent. He had no ego, he was very kind. He was the last person this should have happened to.''
