Four people involved in the supply of a lethal concoction of drugs to two young men who later died have been remanded in custody for sentence.
David McGrath (25), John O'Dwyer (26), Victoria McCormack( 22) and David Maguire (31) all pleaded guilty at Cork Circuit Criminal Court to possessing the drugs for sale or supply.
They all admitted possessing the mixture of MDMA and PMMA at different locations in Cork city on various dates between September 7th and September 10th 2012.
Det Garda Jason Wallace said all four were links in the chain of supply which saw the lethal powder being bought and consumed by friends Liam Coffey (22) and Michael Coleman (22).
Both young men, who were originally from Co Waterford, were pronounced dead by a local GP at Mr Coleman's rented house at Abbey Lane in Kinsale on September 10th, 2012.
The GP, paramedics and gardaí had been called by Mr Coleman's girlfriend Ciara Drummey after both men fell ill after ingesting the lethal mixture of MDMA and PMMA.
Det Garda Wallace said that all four defendants were not aware at the time that the mixture contained PMMA which is slower acting than MDMA but highly toxic.
Judge Donagh McDonagh said he wanted to consider the evidence and various reports submitted on behalf of the defendants and he remanded all four in custody until Friday.
