ORANGE COUNTY, Fla. -- Tempers flared Monday when George and Cindy Anthony arrived at the scene where teams were searching for the body of their missing granddaughter Caylee.

George and Cindy came to Blanchard Park to try to convince bounty hunter Leonard Padilla not to hold a memorial service at the search site Tuesday morning. Video showed Caylee's grandparents talking to Padilla (video | images), but the bounty hunter decided to go forward with it despite their pleas.

Meanwhile, the water search in east Orange County began late after having to wait for permission from Blanchard Park officials. Two divers, hired by Padilla, searched 50 yards of the shore and 15 feet out in the Little Econ River in Blanchard Park (see map). Padilla thinks Caylee's body is in the river.

Padilla also announced Monday that he will be holding a memorial service at 9:00am Tuesday along the river search site.

Padilla and his team focused on the river where a cross was found nearby. He said the FBI is involved in the search, as well, but the FBI has denied that.

"We feel confident enough, we have to, and we have to check it out," he said.

The cross was found hanging on a tree very close to the Econ River, which was the site of a major search effort to find Caylee's body.

"You can't let something like this go because it sounds strange," said Padilla.

A team member from EquuSearch snapped a picture back in August of the cross hanging from a tree. The cross is made from the same type of arts and crafts materials found in Casey's bedroom. Padilla said he is focusing his attention on the photograph.

"We looked at the tree where the cross was hanging and it's not more than 70 yards away from the water's edge," he said.

Despite Padilla's confidence they'd find the girl's body, the murky water prevented dive teams from finding anything Monday.

TINY TURNOUT FOR GROUP'S LIKELY FINAL SEARCH

From 5,000 to 40, the big expectations in the search for Caylee Anthony's body ended in a tiny turnout at another search site Monday near the 417. It will likely be the last time the group EquuSearch will look for Caylee.

Only about forty volunteers were on site to get instructions before Monday's search in a wooded area near Econ Trail along the 417. When they lined up, they were told to be precise in their search and yell for their team leaders if they see anything suspicious.

About 2,300 volunteers also looked for Caylee's remains Saturday and Sunday. They believe a body or a shred of evidence are the only things that may give the community closure.

"The longer everyone searches, there's a possibility evidence will be found," volunteer Cindy Smith said.

The area is so dense with brush and trees, it would be almost impossible to spot human remains anywhere.

"We can bring in the entire military and there's still a small chance that she would ever be found," EquuSearch founder Tim Miller said.

Miller said the case has put his group in debt; they've spent $100,000. He will leave for North Carolina on Tuesday morning to focus on other missing persons cases, but said he may leave some of his volunteers behind.

Miller also said he's frustrated with bounty hunter Leonard Padilla, who started his own search Monday in an area Miller claims isn't even on sheriff's investigators radar.

"There's no evidence to lead anyone to believe there's a good reason to dive. I would only hope it's not for self promotional reasons and turning this into a circus," Miller said.

CINDY ANTHONY SPEAKS OUT ON GMA

Caylee Anthony's grandmother told Good Morning America on Monday people should be looking for Caylee alive, because there's no evidence she's dead (watch video). She lashed out at prosecutors for wanting to put a gag order on the defense and the Anthony family.

Cindy said prosecutors don't want them to talk publicly about tips they are getting that suggest Caylee is still alive. She went on to say they received a tip just Saturday night that Caylee was spotted in Florida. Cindy said she watched surveillance video and believes it could be her granddaughter and investigators are now looking at that video.

HEARING FOR MOTIONS POSTPONED

The case against Casey was expected back in court Monday, but it won't happen due to a scheduling blunder by Casey Anthony's attorney, Jose Baez.

Baez set a hearing Monday to request more evidence from the sheriff's office. The judge was also to hear the prosecutors request for a gag order on the Anthony family.

Baez, though, later said he has another court appearance and can't make it.

CASEY'S EX-FIANCEE'S FATHER ATTENDS SEARCH

The father of Casey Anthony's ex-fiancee showed up at Sunday's search, but did not participate. Richard Grund once thought Caylee Anthony was his granddaughter, because his son Jesse almost married Casey.

"I'm an old New York Italian. When I make you part of my family, you stay part of my family, so Caylee's still part of my family," he said.

Grund claimed that Cindy Anthony led investigators to believe the Grunds had a hand in Caylee's disappearance, but they have since been cleared.

"I wanted to participate in the search, but considering the accusations made against my son and me by Cindy, I figured it wouldn't be the best thing to be in the area when she's found," Grund said.

Casey's former best friend, Amy Huizinga, also showed up in support of Grund. They all said they shared the hope that Caylee Anthony will soon come home for a proper burial.

AUDIO RELEASED OF GEORGE ANTHONY INTERVIEW

Late Friday afternoon, Eyewitness News obtained new audio tapes of interviews with George Anthony. They indicate he feared the worst when Caylee disappeared.

"My, my heart is killing me right now to say it's going into my granddaughter is not, no longer alive," he said (listen to full interview).

He also said, if he lost his granddaughter, he'd probably lose Casey, too.

Those tapes and documents show that George Anthony told investigators he felt something was wrong from the very beginning. The documents focus a lot on interviews George and Cindy Anthony did with sheriff's deputies.

When sheriff's investigators questioned George nine days after Caylee was reported missing, George told them he had "bad vibes" the very first day he got his car back and smelled a rancid smell in the trunk, a smell, he said as a former law enforcement officer, he knows and would never forget. The smell was that of a dead body.

Casey's father George told investigators, "I don't want to believe that I have, have raised someone and brought someone in this world that could do something to another person. I don't want to believe that."

George also told them, "I, I, I believe that there's someone dead back there and I hate to say the word human. Um, I hate to say that."

George told them, when he opened the trunk of the car, he said to himself, "Please don't let this be my Caylee."

But Thursday, Cindy Anthony told Eyewitness News she's holding on to hope.

"No one's brought me a body. No one's proven that she's dead. I'm not gonna give up on someone that I love that easy. And if I did, then what kind of person would I be? I'm not that person," she said (full interview).

But George also told sheriff's investigators that the very first night they found out Caylee was missing, Cindy told him, "We lost her. We lost her." When he asked who, she said "Caylee."

George also told investigators his daughter Casey lives on the edge, that she takes things as far as she can take them and then she piles on more. He said they caught her in lies about work and money and said she's really good with computers.

Casey spent the Tuesday through Saturday around the 4th of July with Amy Huizenga, her former best friend. She told Amy that Caylee was at the beach with the nanny and with Cindy, but no one's met the nanny.

George says Casey has lied to her attorney, Jose Baez. She told him she had $5,000, even though she didn't and then she told him that he'd get the rest after she gets out of the situation.
