Could it be possible that 28 year-old Heath Ledger died of natural causes? According to TMZ it could be.

 it’s now appearing that the level of toxicity (from medication) in Ledger’s system was low enough that it may not have caused his death. These sources say Heath’s heart stopped. It could have been a heart attack but it’s not certain, at least not yet. Although it’s bizarre that a 28-year-old could die of natural causes, it happens.

Authorities also debunk the reports that the masseuse called Mary-Kate Olsen first so the two could remove all the illegal drugs from the apartment.
