FREDERICTON -- New Brunswick Crown prosecutors say they won't appeal a provincial Court of Appeal decision ordering a second trial for Marissa Shephard.

Shephard was convicted in the brutal slaying of 18-year-old Baylee Wylie of Moncton, who was stabbed about 200 times.

Last month, the Court of Appeal concluded that a judge's errors had deprived Shephard of the right to a fair trial.

During the trial last year, court heard that Wylie's body was found in Shephard's burned-out townhouse on Dec. 17, 2015.

According to court documents, the victim, Shephard, and two other young men gathered at her home for "some drug-fuelled excitement" that ended tragically with Wylie being tied to a chair, beaten and stabbed repeatedly with a variety of weapons.

Shephard, who was 20 at the time of her arrest, was the third person convicted of murdering Wylie.

The case will return to the Court of Queen's Bench in the coming weeks to set new trial dates. Shephard will remain in custody pending the new trial.
