Casey Anthony is expected to be released from jail on July 13.

A court official in Orlando, Florida, said Anthony is going to be released from jail next Wednesday following her conviction for lying to authorities who were investigating the death of her 2-year-old daughter, Caylee.

That official said, "The defendant has been given credit for 1,043 days served and at this time, her release date has been calculated to be July 13, 2011."

Anthony, 25, was sentenced to four years in jail earlier Thursday, but she is receiving credit for the time she has already served as well as good behavior.

On Tuesday, a jury acquitted her of murder in the death of her child in 2008.

Following her sentence this morning, Anthony was returned to jail.

Anthony was convicted of four counts of lying to detectives trying to find her daughter. She lied to them about working at the Universal Studios theme park, about leaving her daughter with a non-existent nanny named Zanny, about leaving the girl with friends and about receiving a phone call from her.

Her defense attorneys argued before sentencing that her convictions should be combined into one , because her lies occurred in one conversation with one criminal intent.

However, Judge Belvin Perry disagreed saying her lies were "separate and distinct" and caused many wasted hours for investigators.

Judge Perry also fined her $1,000 on each count.

Meanwhile, prosecutors filed a motion asking for Anthony to pay the costs of the search for Caylee. During her trial, the defense said Caylee was never missing.

Outside the courthouse Thursday morning, dozens of officers were on hand as a small throng of protesters gathered. Some held signs reading "Justice for Caylee," "Arrest the Jury!!" and "Jurors 1-12 Guilty of Murder."

Michell May, a 36-year-old medical assistant from Brunswick, Ga., lamented that whatever the sentence Anthony gets, "it's not going to be long enough."

Despite the verdict, May wanted the judge to sentence Anthony to death or life in prison.

"I just expect that she's probably going to walk and I'm not very happy," May said.

There were also a handful of Anthony supporters, including Tim Allen of Orlando. The 24-year-old cook at a pizza shop held a sign asking Anthony to marry him.

"Everyone deserves a second chance." Allen said. "She's beautiful. Put some makeup on her, she's gorgeous."

Jurors declined to talk with reporters immediately after Tuesday's verdict. But juror Jennifer Ford told ABC News in an interview that it was because "we were sick to our stomach to get that verdict."

"We were crying and not just the women," Ford said in an interview posted on the network's website Wednesday night. "It was emotional and we weren't ready."

Ford, a 32-year-old nursing student, said the case was a troubling one.

"I did not say she was innocent," Ford said. "I just said there was not enough evidence. If you cannot prove what the crime was, you cannot determine what the punishment should be."

The prosecution didn't paint a clear enough picture of what happened to Caylee, Ford said.

"I have no idea what happened to that child," Ford said.

It is not clear what the future holds when Casey is released. Threats have been made against her, and online she is being vilified. More than 17,000 people "liked" the "I hate Casey Anthony" page on Facebook, which included comments wishing her the same fate that befell Caylee.

Tim McCleod, who lives a few doors from Casey's parents, said: "Society is a danger to Casey; she's not a danger to society."

Her family also has been fractured by her attorneys' unproved claims that Casey's father and brother molested her and the contention that her father participated in a cover-up of Caylee's death. When the verdict was read, Casey's parents rose from their seats and left the courtroom. They were in the courtroom again Thursday for sentencing but left without speaking to reporters.

Their attorney, Mark Lippman, has said they haven't spoken with their daughter since the verdict, and he wouldn't say whether they believed she was guilty.

Casey is a high school dropout who, before her arrest, had limited work experience. Her last job was in 2006 as a vendor at Universal Studios theme park.
