jealous teenage girl who prosecutors say threatened to withhold sex
from her boyfriend unless he murdered a rival has been found guilty of
first-degree murder.


Fourteen-year-old Stefanie Rengel was stabbed six times and found
lying in the snow outside her parents' Toronto house on New Year's Day


Today, a jury found the 17-year-old girl guilty of murder.


Prosecutors argued the girl was driven by jealousy and used instant
messaging and sexual blackmail to convince her boyfriend to kill Rengel.

The defence had argued the jury shouldn't draw murderous intent from messages sent over the Internet.

The boyfriend, now 19, faces trial in the fall on a first-degree murder charge.
