The biggest names in the music industry honored singer Whitney Houston Sunday night.
The Grammy Award ceremony was filled with touching tributes to the singer, who died suddenly in Beverly Hills Saturday.
The Los Angeles County Coroner confirmed to NBC News that prescription pill bottles were found in her room, but added that it could take six to eight weeks to determine the cause of death.
"The person could have suffered a heart attack or an embolism or something, and no matter what medications they are taking until we run a tox and see the level and what's in the system, we aren't going to speculate," said Ed Winter.
There were no signs of foul play and investigators say they do not suspect any criminal intent in Houston's death.
