Investigators will search woods in an Orlando suburb for a fifth day Monday.

Dozens of bones have been found, near the Orlando home of missing toddler Caylee Anthony. Bob Kealing tells us why the trail of bones may explain where the body was dumped.

All weekend, two sources speaking on condition of anonymity tell us they've been finding a small trail of bones. Thirty members of the FBI's evidence response team and other crime scene investigators have been sifting through dirt and debris around the area where a child's skull was discovered by a meter reader Thursday.

Sources say it had long light hair, and its mouth was duct taped shut. Investigators say they're still trying to figure out why.

"I just want her to have a good Christian burial. And I want the family to heal."

Bystanders like George Sardinas have been bringing flowers and stuffed animals to the Anthony home, still plastered with Caylee Aanthony's picture and the excavation site about a quarter mile away.

Sources tell us the body had been covered and placed in a garbage bag. The unknown covering, the trash bag, and duct tape are what lead investigators to serve a search warrant on the Anthony family home Friday morning.

Sunday Casey Anthony's lawyer Jose Baez met with a newcomer to the case--George and Cindy Anthony's new attorney.

"We're going to talk and hopefully have something for you later on."

Baez appeared later but would not comment on whether he and his defense team will be getting access to the excavation site.

"We don't have any statements were going to make right now."

Because some of the more than two dozen bones that have been found at the sight were outside that trash bag, investigators believe either the bag was submerged and they floated out or the bones were scattered by animals.

Saturday some of the remains were flown to the FBI crime lab in Quantico, Virginia.

It's expected to take a least a week for DNA tests to determine if the bones, as Casey Anthony's defense team suspects, are those of little missing Caylee Anthony.

One source says investigators suspect the remains were dumped in the area soon after the child's murder.
