ORLANDO -- The search for Caylee Anthony continues this weekend.
Her mother, Casey Anthony, remains in jail with very little to say, but investigators admitted they still believe she holds the key to bringing the toddler home.
George Anthony politely avoided media questions about the search for his two-year-old granddaughter Saturday evening.
Before the door of his garage closed for the night, he did mention his plans to visit his daughter Casey in jail Sunday morning.
That’s one of three visits Casey will be allowed to have this coming week.
George Anthony would not comment on their visit to the Orange County sheriff's office Friday morning or what was taken from their home.
Crime scene investigators with the sheriff's office made a brief stop at the Anthony's home and walked out carrying two large brown paper bags with evidence.
At the time, investigators would not say what were in the bags, but reports have revealed the bags contained gasoline cans, which are now being checked for forensic evidence.
Shortly after leaving the sheriff's office Friday afternoon, George and Cindy Anthony headed over to Daytona Beach for a benefit to raise money for Caylee's search and to aid in the search for other missing children.
Caylee Anthony has been missing for roughly six weeks now.
Sheriff's Office: 'Casey Has The Key'
Could there be new leads in the search for Caylee Anthony?
The question comes just hours after crime scene investigators were seen entering her grandparent's home Friday.
The investigators were in the house for about five minutes, and then left with two large brown paper bags.
The Orange County Sheriff's Office wouldn't comment on what was taken, but said the family is cooperating.
Spokesperson Carlos Padilla said his office has been receiving a lot of tips, and detectives are looking into them.
Casey Anthony's parents met with investigators and the FBI, and both agencies said they're using every resource to find Caylee.
They said the biggest obstacle in the case is Caylee's mother.
"Casey has the key to this. Casey was the last person to be seen with the child and we still believe that Casey knows more than what she's telling us and she's the only one who can tell us something that can turn this around," said Deputy Sheriff Carlos Padilla from the Orange County Sheriff's Office.
Detectives also said the name Zenaida is not as uncommon as they first thought. Casey said she left her daughter with her nanny, Zenaida Fernandez-Gonzalez.
Meanwhile, we're awaiting DNA results from other evidence taken from the Anthony's home and from the trunk of Casey Anthony's car.
Benefit Friday Night For Missing Children
Dozens of people turned out in Daytona Beach for a benefit to help raise money to assist in the search for Caylee.
Friday’s event at Speed Park Motorsports was designed to help all the missing children in the state of Florida.
All the donations will go to the Kid Finders Network, which also was on hand to take photos and fingerprint kids.
As for the Anthony’s, they said they were touched to see all the people who wanted to help, and said their ordeal is teaching things about themselves they never knew before.
George Anthony also said he learned a lot Friday night about several other missing children, and not just his granddaughter.
Cindy Anthony Tells Larry King She's Not A Liar
The grandmother of missing 2-year-old Caylee Anthony weighed in on her meeting with the FBI during another appearance on CNN's "Larry King Live" Thursday night.
Cindy Anthony said her meeting Wednesday with federal investigators went well, but she would not say what information she told.
Cindy told King she thinks she knows who has the toddler, but was on the defensive again about the day she called 911.
"I said whatever I needed to do to get the authorities to come help me," Cindy Anthony said. "I worked on whatever I could to get them out there, so I'm not a liar. I just stretched the truth a little bit. The car wasn't where it was supposed to be, so I said it was stolen, because I didn't have any reason to come to my house. That doesn't make me a liar or a murderer, and that doesn't make my daughter either, just because she had some mistruths."
Caylee On Cover Of 'People'
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.
