The Orange County Sheriff's Office is making national headlines for its investigation into the disappearance of Caylee Anthony.
Carlos Padilla, with the Orange County Sheriff's Office, said Casey Anthony is the last person to have had contact with Caylee, but she refuses to sit down with law enforcement.
"We truly believe she has info that could help us find her little daughter," Padilla said.
Padilla sat down with People magazine for this week's cover story, which was released Friday.
"I honestly can say we've had other cases that made the national media, (but) I don't recall anything more than this. (It's) something that's been phenomenal, unbelievable," Padilla told News 13.
The national attention in this case means investigators have a lot of interviews to watch. Padilla said investigators are watching those interviews as a way to connect the dots and get a picture of what happened.
"Keep in mind, we have a whole unit and also have civilian personnel taking down tips and turning them over to police," Padilla said.
In the article, Padilla said there is no evidence to prove the toddler is dead.
He also said several suspects have been ruled out, including Casey Anthony's boyfriend, who has been fully cooperative. Padilla said that Caylee's biological father is dead, but he would not say who the father is.
According to Padilla, DNA results, including evidence collected from the trunk of Casey Anthony's car and her parent's backyard is expected to be in by late next week.
