Water Found in Her Lungs
As TMZ first reported, authorities believe Houston may have fallen asleep or lapsed into unconsciousness in the bathtub and drowned.
But according to our sources, authorities cannot yet determine whether Houston died before she was submerged in the water or after. We're told there is still a possibility Houston was dead before she went under the water.
Toxicology results will be back in 4-6 weeks.
