From Ronald Cummings' statements, it's clear he believes a stranger took Haleigh.
"If you have my daughter and you're watching this, drop her off somewhere safe, call 911, call the local authorities," Cummings said. "If you've done something with her, tell us where she's at. I'm not out for revenge ... I want my daughter back."
Search For Haleigh Expands
Thursday morning, Hardy said that detectives have followed leads and interviewed everyone connected to the kindergartner and were adding new resources to the search.
"We'll expand our investigation as far as it needs to go,? Hardy said. "As far as whether or not Haleigh is still in the area, that is an unknown."
The Putnam County Sheriff's Office said they must assume Haleigh was abducted because house-to-house searches of the neighborhood Wednesday found no evidence that she wandered away.
Cummings, Croslin and other family members and acquaintances -- even an air conditioning repairman that was at the house Monday -- were interviewed and offered lie-detector tests.
Hardy would not confirm who had taken polygraph tests or discuss the results.
The third morning after an Amber Alert was issued, a low cloud ceiling prevented helicopters from being used, but boats and divers were in the St. Johns River, which is only about 1,000 yards from the mobile home park.
Texas Equusearch, a mounted search-and-rescue group that helped search for missing Orlando toddler Caylee Anthony last fall, arrived in Satsuma on Thursday afternoon.
"A fresh set of eyes and they'll be able to cover some of the terrain that's very difficult to get to and they'll be able to get to it by horseback," Hardy said.
Caylee's grandfather, George Anthony, came to the Putnam County command post on Thursday, met with Ronald Cummings, his family and friends, and offered any support the family needs.
"They need the community's support. They do not need to be judged. They do not need to be scrutinized," Anthony said. "They need your help. (The) community needs to come together to help this family to bring this beautiful little girl home."
Celebrity bounty hunter Leonard Padilla, who was also involved in the Anthony case, has offered a $25,000 reward if Haleigh is returned before midnight Saturday.
The missing girl's loved ones have stayed in a tent yards away from Cummings' double-wide mobile home for most of the past two days as they leaned on each other for support.
Putnam County Sheriff Jeff Hardy said early Thursday that searches for Haleigh by air, ground and water would continue through the day. In addition to dozens of deputies and officers from surrounding counties, the Florida Department of Law Enforcement and the FBI were also involved in the case.
Authorities ask anyone with any information to call the Putnam County Sheriff's Office at 386-329-0800 or the FDLE's Missing Endangered Persons Information Clearinghouse at 888-FL-MISSING.
