Actually, Peter killed Laura to gain her Alpha power but he DID NOT cut her in half. If you listen carefully to what Kate tells Derek in 1.05 'The Tell', the hunters found the dead werewolf body and cut it into pieces. We later learn from Gerard that this is the way the Argents ensure the werewolf stays dead.
