Anna Nicole -- Drugs on the Bed

The first witness in the preliminary hearing over Anna Nicole Smith's prescription drug death testified authorities found a baby bottle of Pedialyte on her bed, along with a bottle of Cipro.

Pedialyte is used to rehydrate children when they experience diarrhea and vomiting. Anna had been battling the flu.

Cipro is an antibiotic used to treat infections.

Anna was found unresponsive in her hotel room on February 8, 2007 at the Hard Rock in Seminole, Florida. Her cause of death was a sleeping med along with 8 other prescription drugs.

Howard K. Stern, Dr. Sandeep Kapoor, and Khristine Eroshevich are charged with fueling a drug addict's habit.

The baby bottle evidence could be important because prosecutors are trying to show Anna Nicole was so incapacitated from drugs she could barely function.
