A University lecturer pleaded guilty to possession of four types of drugs after the death of a 15-year old girl during a party at his home in West London.
Isobel Jones-Reilly, 15, died after going into cardiac arrest at the home of Brian Dodgeon, 61, at an unsupervised party held by his 14-year old daughter in April.
Dudgeon, a research fellow at the University of London's Institute pleaded guilty to four counts of possession, including the party drugs ecstasy, LSD, ketamine and 5-MeO-DIPT, otherwise known as 'Foxy Methoxy.'
Isobel, who lived in Ramsay Road, Acton and was a pupil at Chiswick Community School, died in hospital with the cause of her death due to ingestion of the drug MDMA, more commonly known as ecstasy.
"Isobel took two tablets. Mr Dodgeon's daughter and two other youths took one each. By 3am Isobel had shown signs of deterioration. She had started hallucinating and became very hot and red faced. Her friends wanted to call ambulance but she insisted that they did not because they would get into trouble," prosecutor Nisha Dutt told West London Magistrates Court.
Isobel was taken to St Mary's Hospital in Paddington but was pronounced dead at 6.30am.
Dodgeon's 14-year-old daughter, Beatrice Hadjipateras, and two 14-year-old boys were also admitted to hospital after the party.
Dodgeon and his partner Angela Hadjipateras were away at a party in Hastings at the time.
The court had also heard how Mr Dodgeon had tried to kill himself by jumping off a bridge a week after the youngster's death.
Dodgeon needed brain surgery following the attempt and spent months recovering in hospital.
Dodgeon will be sentenced at Isleworth Crown Court on 18 November.
