A father has described in gruesome detail how he kept his young daughter's decomposing body in the computer room of his home for days after her stepmother starved her to death then stuffed her into a trash can, 'cracking' her bones to make her fit, to set her on fire.

Eman Moss is the father of 10-year-old Emani Moss who was starved to death in 2013. She weighed just 32lbs when she died.

Her stepmother, Tiffany, is on trial for her murder. She is representing herself at trial in Georgia and thinks that 'God' will get her through the case, offering up no other defense.

Eman Moss testifies against his wife on Thursday about how they set their daughter's emaciated body on fire after she starved her to death in 2013

On Thursday, Eman, who is in prison for his role in the girl's death and trying to cover it up, testified against Tiffany.

He is serving life without parole in exchange for pleading guilty and avoiding the death penalty.

He told how she called him on October 24, 2013, to tell him Emani was dead and that when he got home, he felt her cold, limp body.

'She was dead. She was cold. Her essence wasn’t there. She was gone,' he told the court, according to The Atlanta Journal-Constitution.

Instead of reporting her death, Eman hid his daughter's body in the family computer room.

For several days, he continued going to work and returning home to spend time with her corpse and 'grieve', he said.

When he and his wife decided to dispose of it days later, Emani's body was too stiff to be folded over because rigor mortis had set in.

He had gone to Home Depot to buy galvanized trash can, trash bags, charcoal and lighter fluid already. His wife wanted them to bury her but he decided setting her on fire would be more effective, he said.

At midnight on November 1, they decided to dispose of her body, they drove to a rural area with her in the back of the truck then stopped and unloaded the equipment.

Eman's testimony was at times so graphic that jurors covered their mouths in horror

Tiffany is representing herself but has offered no defense other than that she hoped 'God' would get her through the trial

They stuffed her into a trash can, breaking her bones to make her body fit, then threw in charcoal briquettes into the can, sprinkled lighter fluid inside and lit it on fire.

The jury previously heard how Emani's stepmother picked on her because she was not her biological child

Their two other children, whose ages have not been revealed, were with them.

For five minutes, he and Tiffany watched Emani's body burn but when he realized she would not be reduced to ash, he decided to put the fire out.

They loaded the trash can, with Emani's charred remains still inside it, back onto the truck then drove home.

Eman went to work the next day and confided in a friend about he and his wife had done.

When he returned home that night, he told his wife he was calling 911. She reacted by taking their two other children to her mother's.

Police arrived to find Emani's body in the trash can and her father inside on November 2.

Throughout Thursday's testimony, Tiffany showed no reaction as her husband described their gruesome deeds.

He said that he tried to help her cover up her child's death because at the time, she was not allowed to be looking after the 10-year-old.

She had already been caught beating her severely with a belt.

'I was trying to fix the problem I couldn’t fix. I was trying to fix the problem I couldn’t fix.

'I can’t explain it,' he said.

Tiffany has asked no questions throughout the trial.

On Thursday, the public defenders who used to represent her filed a motion with the court asking to be reappointed during the sentencing phase to try to save her life.

They say otherwise she will be sentenced to lethal injection.

Prosecutors have previously told how Tiffany singled out Emani and bullied her while treating her own children well.

She routinely made sure her kids had enough to eat but starved Emani.

Her father initially told police last Saturday that Emani died after swallowing some chemicals. The man later changed his story, accusing his wife of poisoning the 10-year-old.

He eventually admitted that he returned home from work to find little Emani lying in the bathtub and unable to move.

'I'm guilty, I killed my baby,' he told police at the time.
