Legere, an escaped convict who went on a seven-monthkilling spree in 1989, was convicted in 1991of four counts of first-degree murder.
Walsh was part of the prosecution team that secured convictions in all four cases, due, in large part, to the DNA evidence.
The RCMPforensic lab foundthere was only one chance in 310 million thatsomeone else would match the genetic codes taken from semen samples atthe murder scene of sisters Donna and Linda Daughney, and a one in 5.2 million chanceat the scene where an elderly woman, Annie Flam,was killed. There was no DNA found at the murder scene of priest James Smith.
Legere unsuccessfully appealed in 1993 and was subsequently declared a dangerous offender, a designation that allows for permanent incarceration.
Dennis Oland is accused in the 2011 bludgeoning death of his father, prominent businessman Richard Oland.
The jacket had three small bloodstains on it on the right sleeve, upper left chest and on the back and the DNA extracted from those areas matched his father's profile. The chances of it not being the victim's DNA are one in 20 quintillion, a DNA expert has testified.
DNA, or deoxyribonucleic acid,is thegenetic coding found incells.
Oland, 47, was the last known person to see his father alive during a meeting at his investment firm office on July 6, 2011.
The body of the69-year-old multimillionairewas discovered lying face down in a pool of blood on hisoffice floorthe following morning. He had suffered45 sharp and blunt force injuries to his head, neck and hands. No weapon was ever found.
Walsh, who was brought in from Miramichi to hear the high-profilecase,is expected to begin giving his instructions to the jury early next week.
He warned the jurors it could take him up to two days to do so.
