Janet Jackson was by her family’s side at the preliminary hearing for Dr. Conrad Murray, the man accused of killing her brother. The youngest Jackson put on a suit and tie, finishing the masculine look with slicked-back hair and sunglasses as she quickly entered the courthouse after her mother Katherine and sister La Toya.

As Michael Jackson’s personal physician tried in vain to revive him after a drug overdose, Jackson’s children Paris and Prince entered his bedroom, a former employee testified Wednesday.

"Paris screamed, 'Daddy,' and she started crying," Alberto Alvarez, a logistics director for Jackson, recalled as Janet Jackson, listening in the audience of the Los Angeles courtroom, shook her head and Jackson’s mother, Katherine, dabbed away tears.

Alvarez testified in the second day of the preliminary hearing in Los Angeles on an involuntary manslaughter charge against Dr. Conrad Murray. The judge will determine whether there's enough evidence for a trial for the 57-year-old doctor.

According to Alvarez, when Jackson's children appeared that day in June 2009, Murray shouted, "Get them out! Get them out! Don’t let them see their father like this."

At the time, Paris was 11 years old and Prince was 12. Jackson was on his back, his eyes and mouth open, as Murray gave chest compressions and attempted mouth-to-mouth resuscitation, Alvarez says. Jackson was later declared dead at the hospital at age 50.
