Lawyers for the man who killed Dublin teenager Melanie McCarthy in a drive by shooting say he's going to end up at the Central Mental Hospital if his prison conditions aren't improved.
The Court of Appeal has heard Daniel McDonnell from Brookfield Lawns, Tallaght is in solitary confinement at Wheatfield prison and is likely to remain there indefinitely.
Daniel McDonnell is serving life for the drive by murder of 16 year old Melanie McCarthy McNamara in 2012.
He's been described as probably the most at-risk prisoner in Ireland.
In February a High Court judge ruled his year long solitary confinement under 23 hour lock up at Wheatfield Prison breached his consitutional rights to bodily and psychological integrity.
A subsequent ruling concluded he needed more time out of his cell and more social interaction as there was uncontroverted evidence his mental health was suffering.
Both decisions are now being appealed by the prison authorities who say he is at risk and can't mix with other inmates because he's fallen out with 2 former associates on the wing.
Daniel McDonnell's barrister Bernard Condon says creative thinking is required – or his client is going to end up in Dundrum.
