A Supreme Court decision today means it can now be revealed that a 20 year-old woman pleaded guilty earlier this year to first-degree murder in the death of Grade 3 student Tori Stafford.

Terri-Lynne McClintic entered the plea in April in a Woodstock court, but that information was under a publication ban until today.

The ban is lifted now that the Supreme Court of Canada has declined to hear an appeal in the case.

Eight-year-old Victoria, known as Tori, disappeared outside of her school on April 8, 2009.

McClintic and Michael Rafferty, 30, were charged more than one month later and Tori's remains were found in a field over 100 kilometres north of Woodstock.

Rafferty has been committed to trial on first-degree murder and kidnapping charges.

First-degree murder carries an automatic life sentence with no chance of parole for 25 years, but McClintic could apply for parole under the so-called faint hope clause in 15 years.

Tori's death spurred a review of Ontario's Amber Alert guidelines, giving police greater leeway for sounding the alarm in the critical first few hours of a child's disappearance.

The abduction unleashed a torrent of criticism against Oxford Community Police for not issuing an alert after the girl disappeared.
