The woman serving a life sentence for the first-degree murder of Tori Stafford is set to have a trial today on allegations she beat up another inmate.
Terri-Lynne McClintic, 22, will face a charge of assault causing bodily harm in Kitchener, Ont., at what is expected to be a one-day trial.
McClintic pleaded guilty in 2010 to the first-degree murder of eight-year-old Tori Stafford, from Woodstock, Ont.
Sentences run concurrently in Canada, so even if she is found guilty her life sentence remains unchanged.
The charge stems from an incident in January at the Grand Valley Institution for Women in Kitchener, where McClintic is serving her life sentence.
McClintic testified at the trial of former boyfriend Michael Rafferty, who was ultimately found guilty of first-degree murder, sexual assault causing bodily harm and kidnapping in Tori's death, and mentioned assaulting someone in prison.
Under questioning from Rafferty's lawyer McClintic said she had specifically asked to be connected to another inmate in a peer support program and beat her up.
"I confronted her about things that she had said about me," McClintic testified at Rafferty's trial.
"Things escalated and there ended up being an assault."
McClintic agreed with Rafferty's lawyer, who said the woman was on the ground in a fetal position while McClintic kicked her and stomped on her.
"I did assault her," she said.
That is also how Tori was killed, though Rafferty's trial heard conflicting evidence about whether he or McClintic dealt the fatal blows to Tori.
McClintic's lawyer on the assault causing bodily harm charge has said McClintic will not admit to the charge at trial.
Geoff Snow said in May that McClintic will plead not guilty.
Her testimony from the Rafferty trial cannot be used against her at the assault trial because she was compelled to give evidence at the hearing, he said.
McClintic lured Tori away from her school in Woodstock, Ont., at the end of the school day on April 8, 2009, with the promise of seeing a dog.
McClintic shoved Tori in Rafferty's waiting car and the two of them drove about 130 kilometres north to a secluded field, where she was raped and brutally beaten to death.
She died from at least four blows to the head from a hammer and 16 of her ribs were broken or fractured.
The Crown alleges McClintic got into a fight with Aimee McIntyre, who is also serving a life sentence for first-degree murder in the death of her former lover, though a new trial was recently ordered.
McIntyre's trial heard that she drove two men to her ex-boyfriend's apartment, one of them stabbed him six times, then McIntyre drove the pair away from the scene, helped them dispose of the knife and helped wash their clothes.
The two men pleaded guilty to second-degree murder. McIntyre's lawyer had argued that at most she was guilty of manslaughter.
In a decision released in May the Court of Appeal for Ontario ruled that the trial judge made several errors that mean she did not receive a fair trial. The court set aside her first-degree murder conviction and ordered a new trial.
