Meanwhile, the rift between Haleigh's family members could be over for the time being.
The family feud could be seen from the first day Haleigh disappeared, when her grandparents on her mother's side questioned stories Haleigh's father, Ronald Cummings, and his girlfriend, Misty Croslin, first gave to detectives when the girl vanished from her Putnam County home.
Croslin told detectives she went to the bathroom, and that when she returned, the girl was gone.
Haleigh's younger brother was also in the same bed with Croslin and Haleigh.
Grandmother Marie Griffis apologized Saturday as both sides came together to celebrate Haleigh's brother's birthday, and to search for the missing 5-year-old.
"We're going to unite for Haleigh, and tomorrow is Junior's birthday," Griffis said. "He'll be 4 years old."
The Sheriff's Office suspended a dive operation Saturday after a dive team turned up nothing related to the case in a thorough, five-day search of the St. Johns River near Haleigh's home.
The Putnam County Sheriff's Office said more than 250 volunteers joined the dozens of law enforcement officers in the search effort Saturday, including members of Texas Equusearch, but did not find anything.
A spokesman said news Friday that investigators discovered items of interest in the home turned out to be false.
Investigators said the family is cooperating with the investigation.
"Everybody is a person of interest," said Chief Deputy Rick Ryan, with the Putnam County Sheriff's Office. "We're continuing the interviews with family members and friends of family members. We're talking to everybody."
