Actually, it's because of the homemade fireworks that I suspected Izzy. If you remember, Noah and Dawn ended up announcing that someone will close the pool at night due to an accident with Harold at a party. They ended up noticing the accident thanks to Izzy, and her homemade firecrackers. It was on that basis that I suspected Izzy as Mal's intended target, and by extension the one who killed him.
