The coroner called the manner of Houston's death an accident, with no trauma or foul play reported, according to Entertainment Tonight.
A source connected to the investigation told TMZ it was "very possible" Houston suffered a heart attack while in the bath, which may have been triggered by a hardening of her arteries as a result of cocaine use.
Houston was honored with a star-studded memorial and buried on February 19 at the Fairview Cemetery in Westfield, New Jersey, next to her father.
