The Cincinnati mom accused of beheading her infant daughter has been “like a zombie” since the disturbing crime, a prosecutor said, as police released a disturbing 911 call that paints a dark picture of a gruesome scene.The brutal killing has shaken the College Hill neighborhood where 3-month-old baby Janiyah Watkins was found after 6 a.m. Monday, her head severed and her tiny body punctured with 15 stab wounds inflicted by 20-year-old mom Deasia Watkins, police said.The mom placed the large kitchen knife in the infant’s hand and then went back to sleep before a 5-year-old relative came over and stumbled on the carnage.A subsequent 911 call captures the chaos and grief the family felt as they dealt with the fallout of the deadly decision (WARNING: DISTURBING CONTENT).“Somebody please send the police,” an anguished voice is heard on the call, obtained by the Washington Post. “My niece killed our baby. Please. Help me.”The dispatcher tries to get more details, but the caller is unable to continue speaking, begging for help as she cries and wails. When she tries to describe the scene, she falters and hands off the phone to her son in a jumble of sobs“Lady, the baby is on my mom’s kitchen counter with its head smashed,” the son tells the dispatcher. “Can you please just send the police as fast as you can.”The man tells the dispatcher he doesn’t know where his cousin, Watkins, has gone and he urges cops to hurry so they can apprehend her before more harm can be done.The baby has already been murdered, he tells the dispatcher, who asks if the baby is breathing.“Listen lady,” he says, “the baby is deceased.”The dispatcher continues to dig for details, asking where the mom is, what happened and asks the caller to describe the scene, which is so brutal it is almost beyond words.“Look, lady. I don’t want to describe the scene. The (scene) is very, very bad, alright? The little baby’s head is open. Like, open open,” he says. “I’m not going in there to touch nothing, because I don’t want to mess nothing up. I’m not going in there to look, because I’ve already seen it. But it’s very violent. It’s a very violent scene.”Arriving officers found Watkins, covered in blood, asleep. She’s been charged with aggravated murder in what prosecutor Joe Deters called “one of the most disturbing cases I’ve ever seen.”"She's (Watkins) not talking to anybody," Deters told WCPO-TV on Wednesday. "She's like a zombie. We're hoping to get her some medication so she can begin talking."Authorities have long been aware of Watkins, who suffered from mental health issues and was diagnosed with postpartum psychosis after a January incident when she began “acting crazy” and “speaking of demons,” the baby’s father, James Brown, said in court documents.Watkins lost custody of the baby as she was taken for a mental evaluation“Imminent risk of harm exists if the child returns to her surroundings," a judge wrote after a March 6 hearing.The baby had been allowed to live with the woman’s aunt, but it’s unclear how Watkins was able to visit the child – or why she allegedly slaughtered the helpless infant."Until she gets in front of some doctors and talks, it's going to be very difficult to know what her motivation was,” Deters told WCPO. "No matter what the motivation was, no one is going to be able to explain this.”
