MORE: Casey Anthony Murder Trial Live

ORLANDO, Fla. -- Closing arguments are under way in the Florida murder trial of Casey Anthony.

Prosecutor Jeff Ashton told the jury Sunday that Anthony killed her 2-year-old daughter Caylee because she found it difficult to be a parent.

The 25-year-old Anthony is charged with murdering her daughter three years ago and dumping the body in woods near her parents' Orlando home. If convicted of first-degree murder, Anthony could get the death penalty.

Prosecutors say Anthony suffocated Caylee with duct tape and crafted lies to mislead investigators and her parents.

Defense attorneys say Caylee accidentally drowned in the family's pool, and that her seemingly carefree mother was hiding emotional distress caused by sexual abuse from her father.

Anthony's attorneys will give their closing argument later Sunday. The jurors will then begin their deliberations.
