The jury in the trial of a Dublin man accused of the sexual assault and defilement of a child has heard DNA evidence linking the accused and the alleged victim to a blood-stained bedsheet.
Pleas of not guilty were entered by the court on behalf of the 64-year-old, who cannot be named for legal reasons, on all 14 counts after he refused to indicate whether he would plead guilty or not guilty.
The charges included two of sexual assault and 12 of defilement of a child in both Kildare and Dublin on dates between August 1, 2008 and January 6, 2009.
Sarah Fleming, of the Forensic Science Laboratory told prosecution counsel, Ms Tara Burns BL, that she was able to generate a mixed DNA profile matching the complainant and the accused from the analysis of a blood-stained bedsheet.
She told Ms Burns that the likelihood of the sample belonging to anyone other than the complainant was less than one in a billion and less than one in seven million for the accused.
Ms Fleming denied under cross examination by defence counsel Mr John Peart SC, that DNA profiling, despite its “grandiose reputation”, is “often incorrect”.
She said: “I have never heard of an incidence when it was wrong.”
The court had previously heard that the bed sheet the DNA was extracted from was taken from a property in Dublin the accused had access to, which is also the same property where a number of the alleged offences are said to have taken place.
The trial continues in front of Judge Desmond Hogan and a jury of five men and seven women at Dublin Circuit Criminal Court.
