It was a riveting morning of testimony Tuesday in the involuntary manslaughter trial of Dr. Conrad Murray in connection with the death of his former patient, Michael Jackson.

Sade Anding, a Houston cocktail waitress, and a girlfriend of Murray’s, testified that she received a phone call from the doctor at 11:51 a.m. on the morning of June 25, 2009, which is the time prosecutors contend that Murray realized Jackson was in medical distress.

"I started telling him about my day, and that's when I realized he was no longer on the phone. I was just talking, and the next thing, I said 'Hello hello,' and then I didn't hear anything," Anding said.
