Houston had drug and alcohol problems for years, and last May her spokeswoman said she was going back into rehab. The Times reported that days before her death, she had been acting strangely, skipping around a ballroom and reportedly doing handstands near the hotel pool. According to The Times' Gerrick D. Kennedy, Houston greeted people with a warm smile but appeared disheveled in mismatched clothes and hair that was dripping wet.

Police said at this stage of the probe, they do not have evidence that drugs played a role in Houston's death.
