Dr. Conrad Murray not only faced involuntary manslaughter charges in a Los Angeles court Monday, the former doctor for Michael Jackson also faced intense anger from the grieving Jackson family.

After Murray entered a not-guilty plea in court, the family members in attendance fumed.

"He's just trying to save his own behind," Katherine Jackson told reporters, according to E! News. "He killed him."

"He's lying. He's guilty. Nobody was there but him."
