GARDAÍ said last night there was no breakthrough into the murder of a Dublin man whose body was found dumped on Friday in the Wicklow Gap.

The risk of a chance match or a mistake in the DNA evidence against accused man John Crerar is too high to rely on it to convict him of murder, his lawyer told a jury today.

Blood and semen samples that the DPP alleges link former army sergeant John Crerar to the murder of Kildare woman, Phyllis Murphy, remained in Garda lockers for 17 years, a jury has heard.
