"Enough is enough," Guardian Angels Orlando Chaplain "Colorado" said. "When I saw the news of that girl grabbing Mr. Anthony's shirt and trying to pull him out and rocks being thrown against his house (and) people are punching his garage door -- we all have rights. We are American citizens."

Local 6 showed video of protesters trying to drag George Anthony (Caylee's grandfather) into the street during a confrontation. The incident is one of many reported at the home since Casey Anthony (Caylee's mother) was released from jail for the third time.

Colorado said concerned citizens called for the Guardian Angels to stop the attacks in the neighborhood.

"Everybody here, they work for a living," Colorado said. "They need to be able to come and go to sleep at night, and in a safe environment."

Sheriff's deputies have been continually called to the Anthony home in Orange County but they are paid to patrol the entire county, the Local 6 report said.

The Guardian Angels are volunteers. They said they will make citizen arrests if protests are not peaceful.

"We will try to defuse a situation with no violence, but if we have to bring in the police, then we will bring in the police," Colorado said.

Protesters said they are not intimidated by the Guardian Angels' presence.

Since Casey Anthony was released from jail for a third time, protesters have continued to gather outside the home and have become more aggressive.

Some protesters said they want to break the family down.

"(We're here) just to protest," a woman said outside of the home. "It's just to break them down. I think they are just protecting their daughter (Casey) which is the wrong thing to do in this case."

Latest Charges Formally Filed

Meanwhile, prosecutors on Friday formally charged Casey Anthony with three additional counts related to check fraud. Casey Anthony was arrested on the charges two weeks ago.

Casey Anthony now faces13 counts, including grand theft, with more formal charges expected in the future, Local 6 News reported.

Orlando Investigators In California

Orlando investigators traveled to California in the search for Caylee.

Investigators talked with bounty hunter Leonard Padilla, who was one of the few people who spoke with face-to-face with Casey Anthony after he helped bond her out of jail.

Padilla said Casey Anthony told him a different story about where she last saw her daughter.

She allegedly told him that she left the 3-year-old with a nanny at Blanchard Park in East Orange County.

That's a big change from what she told investigators about leaving her with the nanny at an Orlando apartment complex, Local 6's Jessica D'Onofrio reported from Sacramento.

"Mr. Padilla and his co-workers left Orlando rather rapidly and we did not have a chance at the time to interview him," Orange County Commander Matt Irwin said.

Investigators spent Thursday speaking with Padilla in closed-door meetings.

"They've had contact with the family and we are just trying to lock down their statements at this point," Irwin said.

Padilla said the 22-year-old kicked him out of the home after talking with her for 10 minutes, D'Onofrio reported.

Padilla eventually revoked Anthony's bond because he said he believes the child is dead and that she had something to do with her daughter's disappearance.

The bounty hunter also said he believes that murder charges are coming soon.

Investigators may also talk with a friend of Casey Anthony while out west, Local 6 reported.

Officers said they have received more than 4,000 tips concerning the case.

Casey's 911 Call Released

Several 911 calls for help from Casey Anthony were released hours after aggressive protesters allegedly tossed rocks and pennies at her home and attacked her parents.

"There are protesters still outside of our home," Casey Anthony initially told a 911 operator during a 1:30 a.m. call.

It was the second call Thursday morning from the Anthony home concerning the protesters.

"We already called about an hour and a half ago and it took officers 30 minutes to get here," Anthony said. "The protesters are now banging on our garage door and they've still been throwing things at our windows and our garage and now the media is here. My father is going outside and there is going to be a fight. So, please can you send people down here? There is now a physical altercation. You need to send vehicles immediately."

"It is getting physical?" the 911 operator said.

"Yes, it's getting physical right now," Anthony said.

"You see them physically fighting?" the 911 operator said.

"Yes, I see them physically fighting," Anthony said. "We have surveillance."

"OK, do you know if there are any weapons?" the 911 operator asked.

"I don't know if there are any weapons," Anthony said. "I know that my father is outside and so is my mother. So, send as many people as you possible can."

"And, who is this?" the 911 operator said.

"They need to be arrested because this can't keep happening," Anthony said. "We already had six or seven officers out here for almost 45 minutes and they did not do anything. And they are the same punks that were out here all night throwing stuff at our house."

"OK, stay on the line with me," the 911 operator said.

"I absolutely will, but they need to hurry up," Anthony said. "They were…they just left not that long ago."

"The police officers left?" the 911 operator said.

"The police officers just left at about 1 a.m.," Anthony said.

"A media van just pulled up and that is when all of this started happening," Anthony said.

"About how many people are out there?" the 911 operator asked.

"There are at least a dozen people and now two media vans," Anthony said. "And there is actually more people walking in from across the street."

"How many people are actually involved in the altercation?" the 911 operator asked.

"Channel 2 news has everything on tape already," Anthony said.

"How many people are involved in the altercation?" the 911 operator said.

"There are at least a dozen people," Anthony said. "My mom is out there now spraying people with the hose. My father is…they are trying to get them off the property. They are also trespassing on our property."

"Is it still happening?" the 911 operator asked.

"They are still standing on the property," Anthony said. "Yes, they are out there recording it."

"So, what about the physical altercation? Is it over?" the 911 operator asked.

"It's already over, yes," Anthony said.

"So, it is no longer physical?" a man asked Anthony.

"It is no longer physical," Anthony said. "But it was already physical. It's the protesters."

"Who are you?" the man asked.

"I'm the resident," Anthony said. "We have everything on tape, thanks to channel 2 and also our home surveillance."

"Was there any weapons involved?" the man asked.

"Not that I can see, no," Anthony said.

The call continued with Anthony explaining what her parents were doing.

"This needs to be taken care of immediately," Anthony said. "Both of my parents were hit by the protesters."

Deputies then arrived at the house.

Search Taken To Puerto Rico

Also, George and Cindy Anthony are taking the search to find Caylee to Puerto Rico.

Cindy Anthony sat down with a Univision reporter for a one-on-one interview for the Spanish language TV station.

Anthony said she wanted to do the interview because of the large Puerto Rican viewership and she would like for the report to be played in Puerto Rico.

She said the family got tips about Caylee but could not give details about exactly where in Puerto Rico.

In the interview, Cindy Anthony said investigators told her weeks ago about evidence from the body farm.

According to investigators, the evidence suggests that Caylee is dead.

Cindy Anthony said she believes it was an intimidation tactic.
