Forensic experts are to give evidence today at the inquest into the death of Dublin man Terence Wheelock.
The 20-year-old from Summerhill was found unconscious in a garda cell in Store Street Station on June 2 2005 after apparently trying to hang himself.
He spent three months in a coma in the Mater Hospital before dying.
The Dublin City Coroner’s Court is due to hear details of Mr Wheelock’s clothing on the day he was taken to hospital.
Independent experts, commissioned by the Wheelock family, have found they were covered in blood and vomit but gardai have insisted they never saw any of this.
It took a year of legal wrangling before the family’s lawyers managed to secure access to the clothes.
The Wheelocks have been calling for an independent inquiry to he held into Mr Wheelock’s death and their campaign is supported by local TDs Labour’s Joe Costello and Independent Tony Gregory.
