More than seven years after Tasha Rosette was found stabbed to death outside her Surrey basement suite, her former lover has been convicted of her murder.

Rosette, 21, was found stabbed to death outside the door of her Surrey apartment by her twin sister in 2005. She had been stabbed more than 40 times and her throat had been slashed.

Two men, Amjad Khan and Naim Saghir, were arrested and charged with her murder in 2006.  In 2008 they were both convicted, but three years later the B.C. Appeal Court overturned the convictions and ordered a new trial.

On Friday in B.C. Supreme Court in New Westminster, Amjad Khan was convicted of first-degree murder and Naim Saghir was found not guilty.

At the trial in 2008 the Crown alleged Khan wanted to kill Rosette because she was pregnant with his child and refused to have an abortion. Khan testified in his own defence and denied having anything to do with Rosette's slaying or ever raising concerns about the pregnancy.

During this second trial new evidence was entered suggesting two other people had a motive and opportunity to kill Rosette. But in the end, the court accepted the Crown's original theory that Khan murdered Rosette because she had refused to have an abortion.

The original trial also led to an investigation into the conduct of two Vancouver police officers who allegedly failed to warn Rosette after getting a tip from an informant that her life was in danger.
