Mark Nash has pleaded not guilty at the Central Criminal Court to the murder of Sylvia Shields and Mary Callanan between March 6 -7, 1997.
Linda Williams, of Forensic Science Ireland, said on September 29, 2009, she received three self sealed plastic bags containing thread and buttons belonging to the right cuff of Mr Nash’s black pin-striped velvet jacket from Bríd McBride, also of the FSI.
Dr Williams told Úna Ní Raifeartaigh, prosecuting, she got a profile match from the threads but she couldn’t say from “which set of threads it came from.”
“The profile taken from the threads matched Sylvia Shields DNA profile,” she said.
Ms Ní Raifeartaigh asked Dr Williams if the profile was a “full or partial profile?”
“From the threads, it was a full profile with some minor elements” replied Dr Williams.
Dr Williams also said a DNA profile obtained from a “particle” found inside the seam of the right sleeve of the black velvet jacket, matched the deceased Mary Callanan.
The court also heard the prosecution have nearly finished giving their evidence.
The trial continues.
