SAN ANTONIO — A Texas mother accused of decapitating her 3-week-old son screams “I didn’t mean to do it. He told me to!” while her sister pleads 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, cries “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 alive. “Otty, this time I told you to come to me,” Garcia says.

“I tried, but you told me that you died,” Sanchez responds.

“I’m not dead, Otty,” Garcia says. “I’m standing right here talking to you.”

Sanchez, 33, 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.
