Evidence found on and near Caylee Anthony's remains last December are an identical match to items found in the the house where the slain Florida girl lived with her mother and grandparents.

Documents released Wednesday by the State Attorney's Office in Orlando show the same type of laundry bag and plastic bag discovered at the crime scene also were found in the house where Caylee lived.

In addition, investigators told MyFOXOrlando that the duct tape discovered on Caylee Anthony's skull matches duct tape stuck on a gas can at the Anthony home, MyFOXOrlando.com reported.

The documents also quote Detective Yuri Melich as saying, "I immediately noticed that there appeared to be a piece of silver duct tape across the mouth area of the skull. The tape appeared to have been purposely placed there."

Casey Anthony, 22, is in jail on first-degree murder and other charges.

Caylee disappeared when she was 2 in mid-June but wasn't reported missing until a month later. Her remains were found in December in a wooded lot about a half mile from her family's home. The medical examiner ruled her death a homicide.

Last week, a new jailhouse videotaped interview between Anthony and her parents was released in which Anthony describes herself as a victim.

Anthony has insisted that she had nothing to do with her little girl's disappearance and death, saying she last saw her when she left her with a baby sitter.

Police say she made the story up and the sitter doesn't exist.
