SAN ANTONIO (AP) - A Texas mother accused of decapitating her 3ČO-week-old son screamed "I didn't mean to do it. He told me to" while her sister pleaded for an ambulance to bring help in a desperate four-minute 911 call released Wednesday.

Otty Sanchez, who police say told them the devil made her kill and mutilate her only child, screams "I love him" and says she's stabbed herself in the heart and stomach while her sister tries calming down the 33-year-old mother.

At one point during the frantic call, Priscilla Garcia tries reassuring her sister that she is actually in the house.

"I'm not dead, Otty. I'm standing right here talking to you," Garcia said.

After a dispatcher tells Garcia that an ambulance is on the way, the sister moans, "Oh my God, oh my God, oh my God."

Sanchez is charged with capital murder in the slaying of Scott Wesley Buchholz-Sanchez, who authorities found decapitated and grossly mutilated in a bedroom of her sister's house early Sunday. Police say Sanchez chewed off three of her infant's toes and ate parts of the brain.

Garcia tells the dispatcher that her sister has stabbed her child and that blood is all over the bed.

"She's gone crazy last night. She was hearing voices," Garcia said. "She kept bringing me the baby. Finally she calmed down and I took her back the baby. And now I just woke up to hear screaming.

"The baby is dead. The baby's dead. Please, somebody come."

Sanchez is being held on $1 million bond. It was not immediately clear Wednesday whether she had an attorney.

Scott W. Buchholz, the infant's father, said Sanchez suffered from postpartum depression and that she told him she was schizophrenic a week before the slaying. Buchholz, who said he is also schizophrenic, said he wants her to receive the death penalty.

A family member has said Sanchez had been undergoing psychiatric treatment and that a hospital called looking for her several months ago. Gloria Sanchez, the mother's aunt, said her niece had been "in and out of a psychiatric ward."

In May 2008, Otty Sanchez's mother, Manuela Sanchez, called police after her daughter didn't return from a trip to Austin, saying she was concerned about her daughter's safety. Manuela Sanchez told police she suspected her daughter was into drugs and specifically told police she wasn't suffering from any mental issues.
