( CNN ) -- Casey Anthony is responsible for the 2008 death of her 2-year-old daughter Caylee , a report released Thursday by Florida 's Department of Children and Families concludes . A month after a jury acquitted Anthony on murder and child neglect charges , the state agency found that Anthony `` is the caregiver responsible for the verified maltreatments of death , threatened harm and failure to protect '' in her daughter 's death . Carrie Hoeppner , a spokeswoman for the Department of Children and Families , said the report was issued this week as a `` professional courtesy '' after the sheriff 's office and prosecutors finished their work on the case . She added that the state agency is mandated to conduct reviews when there are allegations that a child dies as a result of abuse , abandonment or neglect . The agency had no contact with the Anthonys prior to the girl 's disappearance in the summer of 2008 , Hoeppner added . The Orange County Sheriff 's Office will not take any further action as a result of the report , Capt . Angelo Nieves said Thursday . `` This closes out the DCF case , and it does not create additional follow-up on our part , '' he said . The report said : `` The Department of Children and Families concludes that the actions or the lack of actions by the alleged perpetrator ultimately resulted or contributed in the death of the child . '' The report was signed by officials in the department Wednesday . Anthony is now free . While she was cleared on murder and aggravated child abuse charges , the 25-year-old Orlando woman was convicted on four counts related to misleading law enforcement authorities . She was sentenced to four years in jail on those convictions , but was given credit for the time she had already served between her arrest and the end of the seven-week trial and was released from jail in mid-July . Prosecutors can not appeal the acquittals . The report does not address , or substitute for , judgments regarding the guilt or innocence of the caregiver -- in this case , Casey Anthony -- DCF spokeswoman Hoeppner said . The state report found that Anthony 's `` failure to act '' in the 31 days between the time the girl was last seen and when police were alerted about the case `` delayed and interfered with a law enforcement investigation and best efforts to safely recover the child . '' The agency report noted there were `` no indicators '' that Caylee 's death was caused by physical injury , and it was `` not substantiated '' that she died of asphyxiation -- both points of great contention during the trial . An autopsy performed in December 2008 by the local medical examiner determined `` that the exact cause of death can not be determined with certainty . '' Prosecutors tried , unsuccessfully , to convince jurors that Anthony used chloroform to render her daughter unconscious and then duct-taped her mouth and nose to suffocate her . In its recommendations section , the report said that `` the maternal grandfather '' -- in this case , George Anthony -- `` should have been interviewed for the missing person report . '' Casey Anthony 's defense lawyer had claimed , in the opening argument of the murder trial , that George Anthony knew Caylee had died accidentally and helped cover up her death . Casey Anthony had been investigated by the agency , when state child welfare investigators determined on September 14 , 2008 , that there were `` verified findings '' indicating that Anthony was responsible for `` inadequate supervision and threatened harm '' of her child , although it found `` no indicators of physical injury . '' Exactly a month later , a grand jury indicted Anthony on murder and other charges , and the case was eventually reopened by the Department of Children and Families . No further detail was immediately offered as to why or exactly when the department chose to review the case , or why it came out this week . The report released Thursday officially closes the department 's investigation in the case . In Session 's Lena Jakobsson and CNN 's Melanie Whitley contributed to this report .
