Homicidal traumatic injuries. Increased intracranial pressure due to blunt force trauma to the head." — Ronald Wayne Davies' cause of death, as listed by the Clark County Office of the Coroner-Medical Examiner.

Nobody really knows what happened that day 20 years ago. To understand fully what Chandler surmises happened — and he is emphatic it is only his conjecture — one has to know a little about the architecture of a typical Washington city home at the time.

There weren't many basements at that time. Instead, builders used what was called a "monolithic pour," one massive, continuous application of concrete with footings but no joints. The whole floor of the house was concrete.

In testimony, one physician testified the trauma to Ronnie's head was equal to the circumstances if he'd been dropped from a third-story window and hit his head on concrete. "That had to have been one hell of a blow," Chandler said.

So, while doctors and witnesses effectively shattered DeMille's story that Ronnie was standing at the toilet and passed out, DeMille maintained his innocence throughout the trial.

Chandler, Parrish and others have only the truthfulness of the evidence. Otherwise, they have conjecture.

"He was perhaps picked up by his little feet and swung against something. Swung hard . . . against the bathtub or the concrete of that monolithic pour," Chandler said.

"I said ,'Is Tommy mean to you?' and (Ronnie) would say, 'no.' He'd just shake his head and then he'd say, 'I want some candy,' and I don't know why he would cry, but every time, he cried." — Interview with Jan Snyder, one of Ronnie's baby sitters, who reported the boy had bruises on his arms and legs in the months leading up to his death.
