Continual coverage of the trial of Drew Peterson for the murder of his third wife, Kathleen Savio.

5:30 p.m. Testimony concludes for day

Testimony from Mary Case, a St. Louis County medical examiner who was the only witness in the trial today, has concluded and court is done for the day.

3:20 p.m. 'It is a homicide'

The state's final question to St. Louis County Medical Examiner Mary Case during its direct examination was whether she had an opinion on the manner of death.

"I do," Case said. "My opinion is that it is a homicide, meaning that some other person did it."

3:10 p.m. 'I hope they like to walk'

After yet another sidebar, the jury was led out of the courtroom. A few minutes later, Judge Edward Burmila asked that the bailiff bring the jury back.

"I hope they like to walk," he muttered as the bailiff left the room.

2:20 p.m. Fall wouldn't have knocked out Savio

Medical examiner Mary Case said that it was her opinion that a fall in the tub would not have rendered Kathleen Savio unconscious.

Rapid acceleration of the brain within the skull can cause a diffuse brain injury resulting in concussions, loss of consciousness or death. These injuries are common in car accidents.

In Savio's case, she could not have fallen fast enough to cause her to hit her head hard enough to knock herself out, Case said.

"It's not the type of force we would see from a standing position, falling in a tub and striking the head," she said. "That is not enough significant force to produce a diffuse brain injury."


2 p.m. Cut on Savio's head focus of testimony

Testimony in the Drew Peterson trial resumed this afternoon with St. Louis County Medical Examiner Mary Case.

Case testified that the blow to the back Kathleen Savio's head was not forceful enough to damage the layers of tissue between the skin and the skull.

"It did not penetrate the galea, it did not damage the bone," she said. "It was, you know, whatever force was enough to just damage the skin."
