The inquest into the death of a Raphoe cattle-dealer, Mr Richard Barron has resumed in Letterkenny, Co Donegal.
The inquiry opened in July, almost six years after Mr Barron was found dead on the roadside near his east Donegal home in October 1996.
The death was initially believed to have been the result of a hit-and-run, but gardai opened a murder investigation within days.
An autopsy conducted after the exhumation of Mr Barron's body in July last year by the State Pathologist, Dr John Harbison, had concluded he may have died as the result of a hit-and-run accident.
However, Mr Paudge Dorrian, solicitor for the Barron family, contested the findings, saying an examination by another pathologist could come to a totally different conclusion.
The case led to the arrest of a number of members of the McBrearty family and to an alleged confession to the murder of Mr Barron by Mr Frank McBrearty Jnr. However, the DPP decided not to bring charges against Mr McBrearty.
Claims of Garda corruption and abuse of power in the aftermath of Mr Barron's death by the McBrearty family has led to the setting up of the Morris tribunal into alleged Garda corruption.
