The sheriff's office has questioned Misty Cummings' credibility, saying investigators don't believe Haleigh was abducted by a stranger. Authorities said Misty failed to provide a detailed account of the late evening and early morning hours and called the account of her evening activities "sketchy."
Hardy said Putnam investigators questioned Misty again Tuesday. She and Ronald Cummings, Haleigh's father, remain in custody after they were arrested in January in a drug sting. Both have pleaded not guilty.
When asked if the drug trafficking charges against Misty, Ronald and Hank Croslin Jr. have become a factor in the Haleigh case, Hardy said, "They have a lot of time to sit and think about it."
Sheriff's deputies blocked access on a main road to the St. Johns River each day during the search, and TV news helicopters have hovered overhead.
Haleigh's case was somewhat overshadowed by that of another missing girl - Caylee Anthony, the 2-year-old whose young mother has been charged with murder in her death. Caylee's memorial service was held just hours after Cummings was reported missing.
Investigators followed thousands of leads and searched the heavily wooded community on foot, with doors and by air via plane and helicopter. They also contacted all the sexual predators living in the area to eliminate them as suspects and searched the nearby St. Johns River by boat.
Anyone with information on Haleigh's disappearance or whereabouts is asked to contact the Putnam County Sheriff's Office at 386-329-0808 or Crime Stoppers at 888-277-TIPS.
