GALVESTON, Texas -- Jurors saw the clothes a toddler once known only as Baby Grace was wearing when she died, the plastic box that hid her body, and heard about "Rules for Riley" that were kept in a notebook, KPRC Local 2 reported Monday.

A Galveston County crime scene investigator also opened the blue plastic storage trunk Riley Ann Sawyers' body was kept in until she was found. When he opened it, jurors stood up at their seats to get a better look.

A fisherman found Riley Ann's body inside the trunk, which was floating in Galveston Bay, in October 2007.

Prosecutors presented the physical evidence in the trial of Royce Zeigler II. He was Riley Ann's stepfather and has been charged with capital murder in her death.

Investigators said after Zeigler finally confessed to helping dump Riley Ann's body, they found a notebook in a storage room he rented with a page titled "Rules for Riley."

The nine handwritten pages including "being polite" and "listening to mom and me."

Zeigler told lead investigator Sgt. Michael Barry that he could not stand the way the little girl acted in public and said she needed discipline.

Zeigler said he had decided to leave the baby's mother because of disciplinary and financial problems.

"I think those 'Rules for Riley' are perfect evidence as to sitting down and trying to agree what the rules for, appropriate rules for 2 1/2-year-old should be. And there's not one thing about that that suggests Royce Zeigler is guilty of capital murder," said Dee McWilliams, Zeigler's attorney.

Jurors also saw photos of the house in Spring where Zeigler and his wife, Kimberly Trenor, allegedly beat the girl to death in July of 2007.

Trenor was convicted of capital murder last February and is serving a life sentence.

Zeigler's attorneys admit he was there, and admit he helped hide Riley Ann's body, but they said he did not kill her.

"They tailored this investigation with the theory that both Kimberly and Royce killed her," Zeigler's attorney, Neil Davis III, said. "They wanted him to say, 'I killed Riley'; therefore, if he didn't say it, he must be lying.”

In testimony last week, prosecutors put on witnesses who said Zeigler complained to co-workers that the boisterous 2-year-old needed discipline and that she had never been spanked until her mother married Zeigler and moved to Houston.

Riley Ann was known only as Baby Grace until relatives in Ohio helped identify her through a composite sketch.
