Guilty: Boyfriend caused death of Taggart star's daughter
Louella Fletcher-Michie died at the Bestival music festival an hour before she turned 25.
A man has been found guilty of the manslaughter of Scots actor John Michie's daughter.
Louella Fletcher-Michie died at the Bestival music festival in Dorset in September 2017.
The yoga and dance teacher took class A hallucinogenic party drug 2-CP and died in woodland just an hour before her 25th birthday.
Her boyfriend, rapper Ceon Broughton, 30, had denied manslaughter by gross negligence and supplying the drug, but he was found guilty at Winchester Crown Court on Thursday following a trial.
The prosecution said Broughton failed to take "reasonable" steps to seek medical help for Miss Fletcher-Michie.
The court heard he filmed his girlfriend as she lay dying at the festival site, branding her a "drama queen".
John Michie, 62, has appeared in a number of well-known TV shows, including Taggart, Holby City and Coronation Street.
He gave evidence during the trial, telling the jury how he drove 130 miles to Bestival after receiving a worrying phone call from his daughter in which she was screeching "like a wild animal".
Mr Michie said he begged security staff to let him into the site and waited 90 minutes before being told her body had been found.
Miss Fletcher-Michie was found dead by a security steward in the woodland, 400m from the festival's hospital tent. A post-mortem examination found "2-CP toxicity" and traces of ketamine and MDMA.
Professor Charles Deakin, a consultant in cardiac anaesthesia and intensive care, told the court that she had a 90% chance of survival if she had been given medical help.
Addressing the jury of five men and six women, judge, Mr Justice Goose 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, who performs under the artist name CEONRPG , previously pleaded guilty to supplying 2-CP to Miss Fletcher-Michie and another person at the Glastonbury Festival earlier in 2017.
The Talk To Frank drugs awareness website states that the 2C family of drugs can make you "energised and alert, extra aware of colours, sounds and smells and very sensitive to touch and sexually aroused".
But it warns: "The more you take, the more intense and uncontrollable the experience will be."
In a statement released through Mr Michie's agent shortly after his daughter's death, the family said: "Our hearts are broken by this horrific tragedy.
"Louella inspired all who knew her with her joy of life."
Mr Michie and his wife Carol - a former Hot Gossip singer - have two other children, Daisy and Sam.
