ORLANDO, Fla. – Teeth and more skeletal remains have been found during a search of a wooded area near the home of Caylee Anthony's grandparents, causing officials to expand the search area to more than a half-acre, Local 6 News reported.
The search began last week after a utility worker found a skull and the remains of a child in the woods, located less than a half-mile from the George and Cindy Anthony's home, which they shared with their daughter, Casey Anthony, and Caylee, who was last seen in mid-June.

The remains have not yet been identified.
Casey Anthony, 22, remains jailed on first-degree murder charges in the disappearance of her daughter, who was not reported missing until mid-July. Her trial is scheduled to begin in March.
FBI agents on Thursday continued to assist in the search at the site. Prosecutors visited the search site on Wednesday to ensure the quality of work being done by investigators.
"As we make additional discoveries on the scene here, they will continue to provide that information, properly label it, sort through it, make sure that it's returned to the medical examiner's office as well," Carlos Nieves of the Orange County Sheriff's Office said.
A team of scientists, including anthropologists, a forensic botanist and a forensic entomologist, have been researching insect and plant growth and climate changes in the area in an effort to pinpoint when the remains were left there.
Casey Anthony's attorney, Jose Baez, on Thursday filed a notice of intent to examine debris taken from the search site, requesting that the state preserve all of the dirt, trees, bushes and shrubs so the defense team can thoroughly sift through it.
According to the defense team, hair similar to Caylee's was found and was being analyzed to help identify the remains, Local 6 News reported.
A nearby makeshift memorial displaying stuffed animals, balloons, letters and flowers in honor of Caylee has more than tripled in size since Monday, Local 6 News reported.
