Casey Anthony's Defense Expected to Rest Case

ORLANDO, Fla. (AP) — The defense for Casey Anthony is expected to rest Thursday after calling its final witnesses, though it's still not known if the central Florida mother will take the stand to answer questions about whether she killed her 2-year-old daughter, Caylee.

On Wednesday, the defense may have been dealt a blow when Casey Anthony's father broke into tears when telling jurors about his suicide attempt some six weeks after his granddaughter's body was found. Defense attorneys contend Caylee did not die at the hands of her mother but accidentally drowned in her grandparents' pool and that George Anthony helped cover it up.

Casey Anthony is charged with first-degree murder in Caylee's death. The prosecution says she suffocated the child with duct tape.
