Ronald Cummings spoke out on national TV Monday night, his first public comments since the private lie detector tests taken by his wife last week.

Ronald appeared on the Nancy Grace show and was asked about those tests Misty Cummings took with the search group, Equusearch.

"Well, until I see more physical proof of what's going on, Ms. Nancy, my concerns are still keeping Haleigh's face on the TV," Ronald said to Grace.

Terry Shoemaker, Ronald's new attorney, said despite the negative light the tests have cast on his wife, Ronald stands behind her 100 percent.

"He has no reason not to believe his wife at this point, and he's going to stand by her until something else comes up," Shoemaker said.

Even though it's been six months since Haleigh was last seen, Shoemaker said their focus now is to keep Haleigh's story alive, even if it means taking bad publicity along the way.

"If nothing else, it's gotten Haleigh's name back into the forefront of the media," Shoemaker said.

Ronald sent a message to the person who has his daughter Monday night.

"There's a loving family at home that needs her more than whoever has her, and you don't deserve her, so let her go so she can come home to where she belongs," Ronald said.

Investigators with the Putnam County Sheriff's Office conducted another interview and took part in another search over the weekend as they look for clues in the disappearance of Haleigh Cummings.

Officials said both were prompted by a private lie detector test given to Misty Cummings earlier this month.

Investigators spoke with Tommy Croslin, the brother of Misty Cummings. They interviewed him regarding comments Cummings made while she was being questioned during the lie detector test given by a private investigator.

Channel 4 was told that the test was set up through Equusearch, a search team that has helped in the efforts to find Haleigh.

Saturday, the Putnam County Sheriff's Office took part in a search with members of Equusearch. The search focused on an area mentioned by Cummings during the lie detector tests.

The sheriff's office said neither the interview, nor the search, provided investigators with any new information. Investigators also reviewed the videotapes of the latest lie detector tests, looking for any new leads in the case.

Investigators have said there has been no sign of Haleigh, now 6 years old, since she disappeared in February.

Anyone with information about Haleigh's disappearance is asked to call Crimestoppers at 888-277-TIPS.
