SATSUMA, Fla. -- For the second day, divers came up empty-handed while searching a murky river for a 5-year-old girl who disappeared more than a year ago.

The Putnam County Sheriff's office said Wednesday there's no new information on either the divers combing the St. John's River or the tip that touched off the search for Haleigh Cummings.

The search for her body -- or any evidence in the case -- has been focused this week on the St. John's River, about five miles south of the girl's home.

Haleigh vanished from her father's home in Satsuma, in northeast Florida, in 2009.

Her father's 17-year-old live-in girlfriend, Misty Croslin, was baby-sitting at the time. She told investigators she woke up at 3 a.m. Feb. 10 to find Haleigh gone and a back door propped open with a brick.

The sheriff's office has questioned Croslin's credibility, saying investigators don't believe Haleigh was abducted by a stranger. Croslin is in jail on unrelated drug charges.

On Wednesday, Croslin's cousin -- Joe Overstreet, 20, of Nashville, Tenn., -- held a press conference in his lawyer's office in Nashville to talk about how Florida authorities interviewed him for 30 minutes Tuesday night. It was the third time Overstreet has been interviewed since Haleigh's disappearance.

Overstreet, who was in north Florida at the time Haleigh was reported missing, has not been charged with any crime and said he doesn't what happened to the child.

"If I knew who did it, I would go straight and call the cops and tell them who did it," he said.

Sheriff's officials in Florida are being tightlipped on why Overstreet was interviewed, and why they are searching that particular area of the St. John's River, which is about 70 miles south of Jacksonville.

On Wednesday, curious neighbors watched law enforcement divers use heavy equipment in the water.

"For the family's sake, I hope they can have some closure," said Kellie Thropp, who owns a business nearby. "I can't imagine how they are feeling."
