Deputy District Attorney David Walgren began laying out the involuntary manslaughter case against Dr. Conrad Murray on Tuesday.
Testimony was expected to begin later in the day.
A number of Jackson’s family members were in the courthouse, including his father Joseph, mother Katherine, sisters LaToya and Janet, and brothers Jermaine, Randy and Tito.
LaToya Jackson carried a sunflower, Michael’s favorite flower.
Murray arrived holding hands with his mother.
Murray has pleaded not guilty and he and his attorneys have denied he gave Jackson anything that should have killed the pop superstar.
