Defence lawyer casts doubt over DNA evidence

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.

Mr Crerar's defence lawyer Roger Sweetman SC also suggested that Phyllis Murphy may not have been killed on December 22 1979 and that her body may not have lain in a forested area in Wicklow for 28 days.
