No one has been convicted of killing Caylee Anthony. Her mother, Casey Anthony, was tried for first-degree murder in 2011 and acquitted of every felony charge, and no other person has ever been charged in the two-year-old’s death. The question of who killed Caylee Anthony remains legally unanswered, and the medical examiner was never able to determine a cause of death.
What Is Known About How Caylee Died
Caylee was last seen in mid-June 2008. Her grandmother Cindy Anthony called 911 on July 15, 2008, after Casey admitted the child had been gone about 31 days. Cindy told the dispatcher Casey’s car smelled “like there’s been a dead body in the damn car.”1Department of Children and Families.

Caylee’s skeletal remains were found on December 11, 2008, in a wooded area less than half a mile from the Anthony family home in Orlando. The body was inside a canvas laundry bag with a blanket. Pieces of duct tape were found near the skull, though decomposition and animal activity had disturbed the scene enough that the tape’s original placement became a point of dispute.
The medical examiner ruled the death a homicide but listed the manner as undetermined. Because of the advanced decomposition, forensic scientists could not identify a definitive cause of death. That gap shaped everything that followed at trial.
The Prosecution’s Theory: Casey Anthony Killed Her Daughter
Prosecutors charged Casey with first-degree murder, aggravated child abuse, aggravated manslaughter of a child, and four counts of providing false information to law enforcement. They sought the death penalty. Their theory was that Casey viewed Caylee as an obstacle to the social life she wanted and killed her to be free of the burden. The state argued Casey used chloroform to incapacitate the child, then suffocated her with duct tape over the nose and mouth.
Several pieces of evidence carried the theory:
- Internet searches. The family’s home computer contained searches for “chloroform,” “neck breaking,” and “how to make chloroform.” A forensic software designer initially reported 84 chloroform searches but later corrected that figure downward, acknowledging a software error. Cindy Anthony testified for the defense that she had made the searches after looking up chlorophyll out of concern about her dogs eating bamboo leaves. Prosecutors countered with her work records showing she was at her job when the searches were run.
- The car trunk. Dr. Arpad Vass of Oak Ridge National Laboratory testified that an air sample from the trunk of Casey’s Pontiac Sunfire was “overwhelmingly strong” with the odor of human decomposition and said he “jumped back a foot or two” when he opened the sample container. He also reported “shockingly high” levels of chloroform on a stained portion of the trunk carpet. Cadaver dogs alerted to the trunk, and a hair recovered from it showed characteristics consistent with post-mortem root banding.
- The duct tape. Prosecutors argued the tape was the murder weapon. Lead prosecutor Jeff Ashton told jurors he had “never been able to figure out a reason why somebody would cover up an accident by putting pieces of duct tape over the nose and mouth of a child.”
- Casey’s behavior. During the 31 days Caylee was missing, Casey went to parties, got a tattoo reading “Bella Vita” (Italian for “beautiful life”), stayed with her boyfriend, never called police, and never searched for her child. Prosecutors argued this was consistent only with someone who already knew her daughter was dead.
Casey’s lies to investigators reinforced the state’s picture. She told detectives a nanny named Zenaida Fernandez-Gonzalez had taken Caylee, but no such person existed in her life. She claimed she worked at Universal Studios and walked detectives into the park before admitting she had not been employed there in years.1Department of Children and Families.

The Defense’s Theory: An Accidental Drowning
Defense attorney Jose Baez opened the trial with a different account entirely. Caylee, he said, was not murdered. She drowned accidentally in the family’s above-ground swimming pool on June 16, 2008. Casey’s father, George Anthony, discovered the body and orchestrated a cover-up, disposing of the remains and staging the scene.
The defense called no witness to support the drowning story directly, and no expert testified that the physical evidence was consistent with drowning. Instead, the defense worked to dismantle the prosecution’s forensics. Its experts argued the trunk stain was pre-existing, questioned whether the air-sample analysis was a scientifically accepted technique (noting it had never before been used in a criminal trial), and offered a competing reading of the duct tape. Forensic pathologist Dr. Werner Spitz testified that the duct tape had been placed on the skull after Caylee was already dead. Because no DNA was recovered from the tape, neither side could definitively prove when it was applied.
The defense also suggested Roy Kronk, the meter reader who found the remains, may have moved or tampered with them between August 2008, when he first reported seeing something suspicious in the same wooded area, and December, when he led police to the body. Kronk denied it, and no evidence supported the claim.
To explain Casey’s lies and behavior, Baez alleged she had been sexually abused by her father since childhood and had learned to lie as a survival mechanism. George Anthony denied the abuse allegations under oath. The judge limited how far the defense could pursue that argument, but it had already been put in front of the jury during opening statements.
Why the Jury Acquitted
The trial ran from late May through early July 2011, with 33 days of testimony from more than 400 witnesses. On July 5, 2011, after roughly 10 hours of deliberation over two days, the jury found Casey Anthony not guilty of first-degree murder, aggravated child abuse, and aggravated manslaughter of a child. She was convicted only on four misdemeanor counts of lying to law enforcement.
Judge Belvin Perry sentenced her to one year on each count, running consecutively, plus a $4,000 fine. With credit for nearly three years already served awaiting trial and good behavior, she was released on July 17, 2011.
The jurors themselves did not speak publicly, but alternate juror Russell Huekler explained the thinking in interviews. He said he “didn’t think the prosecution presented enough evidence to sustain a murder charge” and that prosecutors failed to establish a convincing motive: “just because Casey was a party girl did not show why she would possibly kill Caylee.” On the standard the jury was actually asked to apply, he said, “When they explained to us what reasonable doubt was, I definitely had reasonable doubt then.”
The structural gaps in the state’s case matter to the question of who killed Caylee. There was no cause of death. There was no DNA linking Casey to the duct tape. The chloroform figure had been corrected downward after a software error. The air-sample science was novel and untested in court. Prosecutors could show Casey lied and behaved callously, but the jump from those facts to a deliberate killing required inferences 12 jurors were not willing to make beyond a reasonable doubt.
An acquittal is not a finding of innocence. It is a finding that the state did not prove guilt to the required standard. In Casey Anthony’s case, it also means the legal system produced no answer to the underlying question.
What Casey Anthony Has Said Since
Casey Anthony stayed mostly silent for more than a decade. In 2022, she spoke publicly for the first time in a Peacock documentary series and repeated the accidental-drowning account her defense had presented at trial. She said her father controlled the cover-up: “During the 31 days, I genuinely believed that Caylee was still alive. My father kept telling me she was OK. I had to keep following his instructions.”
George Anthony has consistently denied any involvement in Caylee’s death or any cover-up. Casey’s account has not been corroborated by physical evidence or any independent witness. No charges have ever been filed against George Anthony in connection with Caylee’s death.
Could Anyone Still Be Charged?
Casey Anthony cannot be retried for Caylee’s murder. Double jeopardy bars a second prosecution for the same offense after an acquittal. No one else has been identified by investigators as a suspect, and no other charges have been brought. The case is, in the eyes of the law, closed as to Casey Anthony and open as to everyone else, with no active prosecution.
The medical examiner’s ruling still stands: Caylee’s death was a homicide. Someone killed her. But the person responsible has never been established in a court of law, and unless new evidence points to a chargeable suspect other than her mother, that is likely to remain the final word.
