No DNA evidence was found in tests from scene in woods
FORENSIC analysis of clothing from the scene where Elaine O’Hara’s remains were found yielded no DNA evidence, the jury heard.
Other items found by gardai in Vartry Reservoir, including knives and sex toys, also had no DNA evidence.
Forensic Scientist Dr Fiona Thornton told the jury she analysed a number of exhibits in the case, including items found at Killakee Woods on September 2013, as well as from searches at Vartry Reservoir and Mr Dwyer’s home and office.
The items recovered at Killakee included a pair of runners, striped sock, rusty blade, disposable cup and lid.
There was no blood found on the runners or sock and no DNA profile on the rusty blade or disposable cup, Dr Thornton told Prosecution Barrister Anne Marie Lawlor.
Objects found at another nearby site were also tested, including a red bull clip with black tape and wire. There were two hairs on it and no DNA was obtained from these.
A profile was obtained from the two pieces of tape but this was of an unknown male. The profile was not Mr Dwyer’s.
There was no blood on a piece of wood with screws and twine and insufficient material to generate a DNA profile.
