An inquest into the death of a 17-year-old youth in the care of the HSE in Cork has returned a verdict of death by misadventure.

Christopher O'Driscoll went missing from HSE care just days before his death.

He had been accommodated in a Jurys Inn in Cork city.

The inquest heard that a week before his death he had been booked into a hotel for several days by a social worker who used her own credit card as payment.

After the inquest, Christopher's mother said more should have been done for him.

Christopher first came to the attention of social services in 2004 when he was 12 years old.

Over the next five years, up to his death in May last year, Christopher was continually in and out of care facilities, bed and breakfasts and on some occasions in hotels in Cork city, the inquest heard.

It was told that difficulties arose within hours of Christopher arriving in the Cork hotel, which had been paid for by social worker Carmel Walsh.

After complaints were made, gardaí were called to the Jurys Inn.

Christopher was found with a girl in his room and what was described by the hotel’s night duty manager, William O'Shea, as evidence of drug taking.

Mr O’Shea told the inquest that after an argument, he had refunded Christopher the cost of the accommodation in cash.

Mr O’Shea told the inquest he now regards this as a mistake.

The inquest before Dr Myra Flynn Cullinane heard evidence that Christopher had been taking drugs from around age 11 or 12.

Social worker with the HSE Steve Mircile said the teen's general health, both physically and mentally, was not good and that as a consequence there had been huge concern about his care.

Mr Mircile said Christopher smoked cannabis regularly, and at times heroin, and also became addicted to prescription drugs.

He was also known to self harm.

His behaviour led to several court appearances, the inquest heard.
