TORONTO -- A Toronto teen who sexually blackmailed her boyfriend into killing a 14-year-old girl has lost her appeal against her first-degree murder conviction and sentence.
Melissa Todorovic had argued self-incriminating videotaped statements she gave to police should not have been allowed as evidence at her trial.
Todorovic was convicted in the murder of Stefanie Rengel -- a girl she had never met but considered a rival.
Evidence was that the then-15 year old goaded her 17-year-old boyfriend, David Bagshaw, into killing Rengel.
Bagshaw, also convicted of first-degree murder, stabbed Rengel six times and left her to die in a snowbank on New Year's Day 2008.
The Ontario Court of Appeal also dismissed Todorovic's challenge to her life sentence as an adult without parole eligibility for seven years.
