Los Angeles County Coroner's Office coroner investigator Elissa Fleak testified on Wednesday that she found 12 vials of the anesthetic Propofol, determined as the drug which played a vital role in Michael Jackson's death, along with a variety of prescription drugs, lotions and medical supplies from the singer's home after his death.

Fleak testified that she retrieved a largely empty 20-milliliter bottle of Propofol on the floor of Jackson's rented Holmby Hills estate, along with various medications next to the pop superstar's bed the night when Jackson died on June 25, 2009.

Some other items -- prescription bottles of drugs including diazepam,Flomax, Lorazepam, clonazepam (used to treat seizures and panic attacks), anti-insomnia drug temazepam, and the anti-depressant trazodone; a number of lotions and creams; a syringe with the needle missing, were also found, Fleak told the court as the involuntary manslaughter trial against Conrad Murray, Jackson's personal physician, entered 7th day of deliberations.

Fleak told the seven-man, five-woman jury that she also found a urine-filled jug which was seated on a chair in Jackson's bedroom. However, she did not explain further about the jug.

Four days later on June 29, Fleak returned to the mansion to check a second bedroom in the home. She found three bags -- a blue Costco bag, a black bag and a light blue and brown Baby Essentials diaper bag -- each containing more drugs on the top shelf of a cabinet, she said.

The black bag contained three bottles of lidocaine, two of them essentially empty, while the blue Costco bag contained a saline bag which had been cut open, with a bottle of Propofol placed inside. The bottle was essentially empty, Fleak told the 12 panelists.

From the diaper bag, Fleak found two 100-milliliter vials of Propofol that appeared to be full and seven smaller 20-milliliter vials -- three of which were opened, the investigator said.

Fleak is due back on the stand Thursday for more questioning.

Earlier on Wednesday, the court heard a disturbing recording of a conversation between Murray and a seemingly drugged-up Jackson on May 10, in which a barely coherent Jackson laments "I didn't have a childhood" and drowsily slurs, "I am asleep."

The recording was retrieved from Murray's iPhone and part of which was played at the court last week.

The pop icon was heard, in a barely recognizable voice, as Jackson was describing his hope that his planned "This Is It" series of 50-soldout concerts would turn out "phenomenal."

The singer rambled about his plan to open a children's hospital using the proceeds from his tour, saying, "I love [children] because I didn't have a childhood. I feel their pain. I feel their hurt."

Towards the end of the recording, Jackson, after a long pause, could be heard saying, "I'm asleep."

Prosecutors seek to prove Murray, 58, failed to properly monitor Jackson after giving him a lethal dose of Propofol. They contend that the cardiologist "repeatedly acted with gross negligence, repeatedly denied care, appropriate care to his patient, Michael Jackson, and that it was Dr. Murray's repeated incompetence and unskilled acts that led to Mr. Jackson's death on June 25, 2009."

Defense attorneys argued Murray was weaning Jackson off the medication, but that the singer "self-administered" a lethal dose.

The trial is expected to last four to five weeks. Murray, who is set free on a bail of 75,000 U.S. dollars, faces up to four years in prison if convicted of the felony charge.
