Jackson`s mother, Katherine, sister La Toya, and brothers Randy and Jackie sat in the second row of the courtroom during Tuesday`s opening session.

`I looked at Alberto because we knew Dr. Murray was a heart surgeon, so we were shocked,` Muhammed, the third witness on the opening day of a hearing said.

When defense lawyer Ed Chernoff asked if perhaps Murray was only asking for help because he was tired, Muhammed said `The way that he asked it is as if he didn`t know CPR.`

Prosecutor David Walgren earlier said that Murray used `ineffectual CPR with one hand while the patient was prone on a soft bed.` Two hands with the patient prone on a hard surface is the proper method, he said.

Jackson died two hours later and Murray is facing a manslaughter charge in the pop star`s death as the prosecutors say he delayed calling 911, seemed not to know CPR and misled paramedics and doctors. The hearing is expected to last two or three weeks, with 20 to 30 witnesses testifying.
A coroner has concluded that Jackson died from `acute propofol intoxication.` Propofol is a powerful anesthetic used to `put people under for surgery` and the benzodiazepines were sedatives Murray later acknowledged giving Jackson in the morning before his death.

Murray`s defense team has hinted it would argue that Jackson was under pressure from the concert promoter, which led him to demand treatments to help him sleep.

Murray, hired as Jackson`s personal physician while he prepared for his concert tour. He remains free on $75,000 bail.

Murray was born on February 19, 1953, in St. Andrews, Grenada. At the age of seven, he relocated to Trinidad and Tobago to live with his mother, where he became a citizen and finished high school. In 1980, two years after first visiting Houston, Texas and getting a chance to introduce himself to his father, Murray returned to Texas to enroll at Texas Southern University, where in just three years he graduated magna cum laude with a degree in pre-medicine and biological sciences. From there, Murray followed in his father`s footsteps and attended the primarily African-American Meharry Medical College in Nashville, Tennessee.

Upon graduating Maharre, Murray enrolled for additional training at the Mayo Clinic in Minnesota and then completed his residency at Loma Linda University Medical Center in California. Other training stints followed; he studied at the University of Arizona on a Cardiology Fellowship, and landed back in California, where he eventually worked as the associate director for the interventional cardiology fellowship-training program at Sharp Memorial Hospital in San Diego.

In 1999, Dr. Murray left California for a second time and struck out on his own, opening up a private practice in Las Vegas.
