More Shocking Revelations in Anna Nicole Case

Toxicologist testifes about her frail health, while bodyguard says he saw Howard K. Stern injecting her with drugs

Hope you've eaten lunch, because if you haven't you might lose your appetite.

Yes, we have more details from the Anna Nicole Smith drug-peddling case.

Florida-based medical examiner Dr. Harold Schueler told the court today that the former Playmate was seriously ill in the days before her death, suffering from a abscess on her buttock from injections of drugs. The condition may have contributed to her drug-fueled death on Feb. 8, 2007.

"[Infections] would have had an impact on her ability to withstand the drugs," the doctor said, reducing her tolerance to sedatives and muscle relaxers she had been taking for pain, anxiety and insomnia. "Her respiratory system could also have been compromised."

In other words, it wasn't just a minor booboo.

Meanwhile, former bodyguard Mo Brighthaupt testifed that he saw Smith sidekick/defendant Howard K. Stern injecting her with medication on at least five occasions after the death of her son, Daniel.

Still waiting in the wings to take the stand: Smith's baby-daddy, Larry Birkhead.

Schueler and Brighthaupt's remarks came in day two of the preliminary hearing for Stern and Drs. Khristine Eroshevich and Sandeep Kapoor, who are facing a litany of felony counts for conspiracy to furnish Smith the drugs that led to her death. They have all pleaded not guilty.

The hearing is expected to last two to four weeks. At the end, the judge will decide whether there is enough evidence to warrant trial.

Yesterday, the hearing kicked off with the lead investigator in the case revealed some rather goulish details about what police uncovered about Smith's final days, among them that the buxom blonde was found lifeless, lying in her own feces in a hotel room at the Seminole Hard Rock Hotel and Casino. Detectives also found bottles containing hundreds of prescription pills in her room, many of which Smith obtained through various aliases.

The defense has argued that most of the prescription medication found in Smith's system was considered therapeutic and far below the dosage levels doctors normally prescribe.

Birkhead, who has been raising his and Smith's daughter, Dannielynn, is expected to take the stand later today or Thursday.
