ORLANDO, Florida (CNN) -- Prosecutors will not seek the death penalty for a Florida woman charged with killing her missing 3-year-old daughter, according to court documents filed Friday.
Casey Anthony has been charged in an indictment with the premediated murder of daughter Caylee.
"It is not in the best interest of the people of the state of Florida to pursue the death penalty as a potential sentence," prosecutors concluded, according to the document.
"Therefore, the state of Florida will not be seeking the death penalty as to Casey Marie Anthony."
Anthony, 22, is charged with killing her daughter, Caylee Anthony, in a case that has received national attention. She was arrested last month and faces charges including first-degree murder in the disappearance of Caylee, who has been missing since June. Watch newly released jailhouse tapes »
She could face a sentence of up to life in prison.
Anthony waited about a month before telling her family that Caylee was gone. Cindy Anthony -- Caylee's grandmother and Casey Anthony's mother -- called the Orange County, Florida, sheriff July 15, saying her daughter would not tell her where Caylee was.
When questioned, Anthony gave conflicting statements to police, including some that were later disproved, according to hundreds of documents and investigative reports released in the case.
She claimed she dropped Caylee off with a baby sitter, but when police checked out her story, they learned that the address Anthony supplied belonged to an apartment that had been vacant for weeks. The woman Anthony named as her baby sitter told police she did not know her.
Investigators previously have said cadaver dogs picked up the scent of death in Anthony's car, as well as in her parents' backyard. They also said air quality tests conducted by the FBI found evidence consistent with human decomposition and chloroform in the trunk of Anthony's car.
A neighbor told police that Anthony had asked to borrow a shovel. Also, analysis of Anthony's computer found she had visited Web sites discussing chloroform, as well as Internet searches of missing children, according to information released in the case.
Last month, Florida 9th Circuit Judge Stan Strickland denied prosecutors' request to impose a gag order in Anthony's case, saying he could not state that continued publicity would pose a threat to her trial, or even that a gag order would stem the flood of media attention.
