Memphis male and female babysitter are charged with murder after one year-old girl in their care died of unspeakable injuries

Two babysitters are accused of beating an infant girl so badly she was bleeding from her rectum before her death.

Kiya Moore, 21, and her boyfriend Dejon Smith, 34, were charged with first-degree murder after Moore's one-year-old niece Kali Moore was found dead.

The baby girl was rushed to LeBonheur Children's Hospital in Memphis about 3am on Saturday and pronounced dead at 4.01am, police said.

Doctors said she had a skull and neck fracture, massive bruising on her back, and rectal bleeding when they examined her body.

Further examination discovered a brain bleed, bruised kidney, high enzymes in her liver consistent with abdominal trauma, and blood in her lungs.

Moore's sister Kyera Moore, in a series of heartbreaking Facebook posts, insisted her sister was innocent and explained the bruises and rectal bleeding.

'Please, my sister didn't do it... my baby has birthmarks on her back that never went away and rectal bleeding is caused from her being constipated,' she wrote.

Kyera explained that the constipation was so bad that she she used Vaseline and frequently fed Kali green vegetables so she could go to the toilet.

'My sister ain't did s**t, that's just the n***a she live with,' she insisted. Police declined to comment on her claims.

Kyera left her daughter, who only turned one in June, with the couple about 5pm on Thursday in what was believed to be her home.

Detectives found no baby food in the home on University Street in Memphis, and it was not clear where the baby was sleeping.

Moore and Smith gave conflicting statements to police blaming each other for Kali's death after they were arrested, as detailed in a charging affidavit.

Smith claimed he heard Moore yelling in the back room and the baby crying, then her slam Kali into the floor, walls, and wooden furniture six to 10 times.

He told police that when he asked her what she was doing, she said it was nothing and that the baby was crying too much and getting on her nerves.

When Smith entered the room, he claimed, Moore stopped and he saw Kali was unresponsive and began CPR, stopping to pour cold water on her.

When Kali didn't wake up, Moore called a family member to take her to hospital.

Smith claimed Moore told him Kali was injured when she fell off the bed and hit her head on the nightstand.

Smith has two children of his own from an earlier relationship, one about to start kindergarten.

Moore claimed she went out and left Smith alone with Kali and when she came home, the infant was unresponsive and he refused to tell her what happened.

Instead, he allegedly told her to say she fell asleep holding Kali and the child fell out of the bed and hit her head on the nightstand - just as he claimed she told him.

Moore agreed that it was she who called a family member to take Kali to hospital.

Police decided to charge both of them with first-degree murder, aggravated child abuse, and aggravated child neglect.

Kyera appeared to have learned of her daughter's death later on Saturday morning when she began a series of mournful Facebook posts.

In several posts she begged for God to kill her and let her daughter live instead.

'Please take me lord please I'll do anything pleaseeeeeee god pleaseeeeeee take me,' one of them read.

'My heart my literal heart in tiny human form is gone... why god please tell me why help me understand why.

'My reason for not giving up on myself is gone... what [am I] supposed to do now?'

Kyera's most recent post wondered if her daughter's death meant she didn't deserve her, and explained how Kali kept her depression at bay.

'I swear I was great to her I loved her with my whole heart she wanted and needed for nothing,' she wrote.

'She knows she was loved by everyone and made anybody she came into contact with happy y'all, I swear she was a angel and didn't deserve this.'
