Yes. According to Grime a deposit was found (presumably blood) from which Attracta Haron's DNA was extracted.
This is why the dogs come to investigate even after a body is found.
BLOOD found in the boot of Meg Walsh's car matched her DNA, her murder trial heard yesterday.
The 35-year-old mother-of one's body was recovered from the River Suir on October 15, 2006 after she had been missing for two weeks.
Michael Burlington, a forensic scientist, yesterday told Dublin's Circuit Criminal Court that DNA matching both Ms Walsh and Mr O'Brien was discovered in the boot of her car.
Her blood was also found on the hardboard spare wheel cover, which had also been thrown away and sections cut from both the hardboard and the mat which were found in a nearby housing estate.
There were also patches of Ms Walsh's blood on the back of the driver's seat and the inside of the driver's door.
No blood was found in a detailed search of the house or the garden shed or dog house.
