Jury hears details on how these investigators narrowed in on Wright family in the 1998 death of Renée Sweeney
The jury in the Robert Steven Wright murder trial heard today from two forensic science experts, detailing for the court the profiles created from the DNA evidence, as well as the fingerprint identification as part of the investigation.
The person who used new technology to provide the DNA sample the company used, Tara Brutzki, testified today. DNA is a genetic blueprint or set of instructions for all living things, Brutzki said, and greater than 99 per cent of our DNA is the same in every human, the basic code for creating our general form, shape, organs.
First, she was able to identify and create a profile for four individuals and different DNA samples found on the evidence collected and submitted by Sudbury Regional Police from the scene of the crime, as well as the dog-traced path that located the jacket and gloves. Brutzki testified she also examined the blood-soaked cotton gardening glove, Sweeney's right hand nail clippings and the jacket, referred to by Brutski by its brand, High Sierra. Brutzki testified she could exclude John Fetterly as the source of the DNA under Sweeney’s right fingernails.
Next to be compared was the jacket, and what Brutzki referred to as a piece of “debris” that had fallen from the nail into the sealed storage cup. Brutzki testified this was the most “fulsome result,” in that it could be matched to another sample in all 15 locations needed. Robert Sr. could not be excluded as the donor of the DNA sample on the white gloves, described as gardening gloves. Wendy Wright was excluded as the mother of this sample.
Also today was testimony from OPP Sgt. Jeffrey Myatt, who is an expert in fingerprint identification and shoe print identification.
