ORANGE COUNTY, Fla. -- A woman accused of not reporting her 2-year-old daughter missing for five weeks has apparently told so many lies, investigators said they still don't know what to believe in the mysterious case.

"As we continued to investigate, we've found more inconsistencies in the mother's story so we continue to look for witnesses and people who may have additional information," Orange County sheriff's Sgt. John Allen said during a Thursday news conference.

Casey Anthony, 22, was taken into custody Wednesday after her daughter's grandparents called Orange County sheriff's deputies over concerns about the well-being of Caylee Marie Anthony, 2.

Detectives said when they contacted Anthony it was determined that she apparently never told anyone that Caylee has been missing since early June.

Investigators said what Anthony has said so far during the investigation has been lies, Local 6 reported.

Judge Questions Mother

Thursday, Orange County Judge John Jordan asked Anthony where her daughter was.

"Mrs. Anthony, the court would say to you, 'Where is Caylee Anthony?' Jordan asked. "But I can't force you to answer that question but that is the question I leave with you. Do you understand?"

"Yes, sir," Anthony said.

Anthony did not say anything else.

"You left your 2-year-old child with a person who does not exist, with a person who does not exist in an apartment you can't identify and you lied to your parents and friends concerning your daughter's whereabouts," Jordan said during Anthony's appearance.

Anthony did not respond.

Tips Offered In Case

During the news conference, Allen said people have already provided "helpful" information in the case but some specifics remain unknown.

"We have been able to talk to different people who have called in since you have put our bulletin out and some of those people have given us information that has been helpful," Allen said. "But we can't say exactly when the child disappeared."

Allen asked for more help from the public.

"Anybody who may have seen the child and mother together during the middle of June or since the middle of June, we need those people to call us as well," Allen said.

Allen also said detectives have done some searches and have taken in some electronic equipment in the case.

Detectives are still searching for the child's father.

Anthony Says Doing Own Investigation

Meanwhile, when detectives initially questioned Anthony, she told them that she was doing her own investigation into her daughter's disappearance during the last five weeks, Local 6 reported.

The woman also said she saw movies and reports that if people in similar situations went to police, they had gotten hurt.

Anthony said her daughter was with a baby sitter at the Sawgrass apartments but on June 9, the sitter did not answer the door.

Detectives said they checked with apartment management and learned that no one has lived in the apartment for five months.

Late Wednesday, Caylee's alleged baby sitter was tracked down by detectives and the woman said she has never cared for the missing child.

Officers said she admitted to lying throughout her interrogation.

"It is difficult to sort through what we are being told," Allen said.

Mother Shows No Emotion

During questioning, detectives said Anthony did not show any emotion over the loss of her child. She did not cry or give any indication she was legitimately worried.

"It appears to the court that you care so little for your child that you did not even report her missing until five weeks later," Jordan said Thursday.

Since investigators cannot get a straight story, they said they are focusing on finding Caylee.

"I feel the more media exposure we have, the quicker we can bring Caylee home and that is the whole point of all of this -- to bring Caylee home safely," Caylee's grandmother Cindy Anthony said. "I kind of felt hopeless last night but I kind of felt hopeful today."
