An Orange County Sheriff's Department official confirmed to Local 6 that investigators will be talking with possible witnesses outside the state for clues into the whereabouts of the child.

The move comes after the 3-year-old's mother, Casey, was arrested, for a third time.

Orange County sheriff's deputies took Anthony, 22, into custody Monday as she visited the jail to meet with her case manager about other charges.

Detectives have said lab tests show Caylee's decomposing body was in her mother's car, and Anthony is their only "person of interest" in the girl's disappearance.

42 Police Calls Since July 15

The Orange County Sheriff's Office call log shows officers have been called to the Anthony home 42 times since July 15.

Deputies said 38 of the calls have been for disturbances, including a scene over the weekend when a mother brought her young children to the Anthony home late night.

During the incident, a 9-year-old's arm was slammed in a car door.

The Department of Children and Families is investigating the child's injury and why he was at the Anthony home at 12:30 a.m. on Sunday.

Neighbors said aggressive protesters are becoming a safety hazard.

The home owner's association filed an injunction to try to keep the protesters away from the neighborhood.

A judge could rule this week.

About 100 families are expected to meet Tuesday night at a HOA meeting to discuss what options they have concerning the protesters.

Expert: Casey Managed Emotions Well

A series of responses given by Anthony during police interviews are not consistent with a desperate mother who wants to find her daughter, a psychologist told Local 6.

"Most people who are interviewed by police officers don't manage their emotions that well," Dr. Deborah Day said of Casey Anthony during questioning over her daughter. "They get upset, they get agitated and they get angry."

Audio recordings of interviews conducted by investigators with Anthony were released Friday by the Orange County Sheriff's Office.

Day listened to the interviews and said she believes Anthony's tone and responses are detached.

"It is inconsistent," Day said. "That's a detachment. She is able to push her emotions aside during these interviews. I think she knows something. I don't know if she knows where her daughter is but she knows something."

In the taped interviews on July 16, detectives caught Anthony in a string of lies.

Day said Anthony managed the stress of questioning disturbingly well.

"What happened to Caylee," an investigator asks on the tape.

"I don't know," Casey Anthony said.

"Sure you do," and investigator said.

"I don't know," Anthony said.

"Listen, something happened to Caylee," an investigator said. "We're not going to discuss where the last time you saw her (was). I'm guessing something bad happened to her some time ago and you haven't seen her, so that part is true -- is you haven't seen her because she's somewhere else right now."

"She's with someone else right now," Anthony said.

"She's either in a Dumpster right now, she's buried somewhere, she's out there somewhere and her rotten body is starting to decompose because what you're tellING us...," an investigator said. "Here's the problem. The longer this goes, the worse it's going to be for everyone. Right now, everything you've told us -- we've locked you into a lie. Every single thing that you've told us has been a lie."

Day said the only time she heard Anthony get emotional on released tapes is when she talks about her relationship with her mother, Cindy. and not her daughter, Caylee, Local 6's Jessica D'Onofrio reported.

A detective was pressing Anthony about how she wasn't living up to her mother's expectations.

Anthony has admitted to lying to several times during the police recordings but never gives any reasons why she is lying, D'Onofrio reported.
