Police reportedly searched again near the Carter Glen condominiums, where 41-year-old Smith lives.

Parker was last seen on Nov. 17, 2011, when she dropped off her twin children at their father's townhouse. Smith was reportedly the last person to see her. He was named the prime suspect in the case, but no charges have been filed.

Some bones were uncovered during Sunday's search, WKMG reports, but it was undetermined whether they were human or animal bones.

Officers also searched the wooded area off Goldenrod Road in the Lee Vista area, and more volunteers sourced the woods by Lake Moss Park, according to WKMG.

Parker is described as a white woman, about 5 feet 6 inches tall with short dark brown hair. Anyone with information about Parker's whereabouts is urged to call the Orlando Police Department at 321-235-5300.
