Ceon Broughton has been found guilty at Winchester Crown Court of the manslaughter of Louella Fletcher-Michie and supplying her with party drug 2-CP before her death at a music festival.
The defendant showed no emotion as the verdict was announced by the foreman of the jury and the court received the announcement in silence.
Broughton then sat down with his hands held together in front of his face as the judge, Mr Justice Goose, said he intended to sentence him on Friday.
The judge said: “The defendant will remain in custody.”
Addressing the jury of five men and six women, he said: “Thank you for all the work you have put into this case.
“The next stage of the process is to go on to sentencing, that will be in the morning.”
Broughton called out to his barrister and said: “Text my mum.”
