Dr. Allan Metzger, a Beverly Hills physician, testified Monday that Michael Jackson asked information from him regarding sleep medicines. He also said that Jackson opted for intravenous rather than oral medication.

This was the first time where another physician besides Dr. Conrad Murray appeared before the jurors. In defense of the former, Metzger mentioned that Jackson announced that he wanted "some form of anesthetic" at a meeting on April 18, 2009, in his home, but failed to mention any specific brand. "I think he used the word juice."

This drug would later turn out to be propofol, the surgical anesthetic that caused his untimely demise.

The defense called Metzger to the stand to prove that Jackson was looking for and purchasing drugs from other doctors while employing Murray as his full-time physician.

Jackson was already suffering from sleep problems which seemed to be incurable by common medicine. But Metzger emphasized that he advised Jackson not to use these kinds of drugs for insomnia, and only prescribed two oral sedatives instead.

He also denied being paid by Jackson to deliver propofol to his home.

"Particularly after performing, he could not come down. Many medicines just did not work," Metzger said under cross-examination by Deputy Los Angeles County District Attorney David Walgren. Furthermore, the pop icon admitted to him that he was "fearful" about his planned comeback tour.

Metzger has long ties to the Jacksons. He previously treated Michael for lupus, went with the pop star on his 90s tour, and recorded his wedding with Debbie Rowe on video.

This connection, however, has gone under scrutiny when he prescribed hepatitis B vaccination to Janet Jackson using another name, "Ricardo Macchi", which is actually her chef. This resulted in a reprimand from the medical board on September 2000, where his defense was doing it for Janet's "anonymity".

In 2009, he claimed that he has not treated Jackson for many years. "I am not at liberty to discuss Michael's medical care," he said.
