TORONTO - Prosecutors in Toronto will ask the courts to give a teenaged girl convicted in the murder of a 14-year-old girl an adult sentence.

Stefanie Rengel was lured from her home on New Year's Day, 2008, stabbed six times and left to die in the snow.

The teenaged girl, now 17, was convicted of first degree murder yesterday.

Jurors heard she considered Rengel a rival for her boyfriend's attentions and offered her boyfriend sex if he'd kill Rengel.

The Rengel family says it hopes the sentence that's handed down will send a clear message that murder at any age has serious consequences.

The 19-year-old man accused of stabbing Rengel is charged with first degree murder and will face a trial in the fall.

Neither of the accused can be named because they were under 18 when Rengel was killed.
