A woman was found covered with bite markings under a comforter after she was 'beaten with a hammer', a court heard.
Sam Varley, 44, was discovered with face down on her bed with blood under her head, Leeds Crown Court was told.
A post -mortem discovered that she had suffered human bite traces on her right pols, several rib fractures and injuries consistent with hammer magazines.
The police were warned on 12 February upon receipt of a call from 999 of a concern that told how she had not seen her for a few days.
Officers discovered the body of Sam at the house she shared with Warren Spence on Brown Hill Terrace, Leeds.
Spence denied a complaint between 7 to 13 February to 13 February last year. He was not present at the address where officers found evidence of drug use before they discovered Sam's body.
Public Prosecutor Stephen Wood told how officers found Sam immobile in her bed.
He said: 'When they enter the bedroom herself, officers pulled the comforter back to the bed and that revealed the body of Mrs. Varley. She lay down on the bed with her face. It was clear to the police in the bedroom that she had died. '

A hammer and her lumps were found from the house. Traces of Sam's DNA were found on the hammer while the DNA of Spence was found in three samples taken out of the hair
A mobile phone, later attributed to Mr. Spence, was also discovered under the body of Sam.
Wood said: “The police quickly established that Mrs. Varley had a relationship with the defendant Warren Spence and apparently he was not at the flat and so he was declared by the police as a suspect for the murder of Mrs. Varley.”
The court heard that Spence, 54, had stayed with a friend before he went to Scarborough, where he was arrested from February 15.
Wood said that Spence gave a false name and date of birth to officers before he was arrested. He answered 'no comment' in both two interviews.
A post -mortem examination of Sam's body discovered that she had injuries, including bruises on her head, and injuries consistent with several strokes to the face, as well as 'shaped -shaped scraped wounds' consistent with a blow from a hammer.
Dr. Christopher Johnson, a forensic pathologist, released the post-mortem 'identified injuries at the back of the trunk and he identified that they had revealed' round 'shaped scrapes', said Mr. Wood.
'Dr. Johnson found the hammer a suitable candidate for these round injuries. “
The research also showed that Sam had “had been pulled out of her strong” and had suffered 25 separate rib fractures – of which 23 were completed.
She also had human bite traces on her right wrist, forearm and left tibia and injuries to her lower limbs.

The public prosecutor said there were indications that Sam Morphine consumed to 'high and potentially deadly toxic level', probably because of an abuse of heroin.
There were also indications of the presence of cocaine and that Sam had consumed alcohol, he said.
But although this substance abuse was considered enough to death by Dr. To cause Johnson, the pathologist was of the opinion that Sam's breast injuries 'played a central role' in her death.
The court also heard that Before he went to Scarborough, Spence had spent time with a friend, Luke O'Connor.
Wood said: 'He was traced by the police. He knew Mrs. Varley about two years prior to her death. He also knew that the suspect was Mrs. Varley's boyfriend and called him 'WOZ'. He knew the suspect about 6 to 8 months prior to the death of Mrs. Varley. '
The court was told that he last saw Sam during an occasion where he had gone to her flat and could hear a fight.
Wood said: “He described it as a shout between a man and a woman, but he wasn't sure if the noise was from Mrs. Varley's flat or higher.
“He knocked on the door and Mrs. Varley answered and she said it wasn't a good time, and he should come back later. Mr O'Connor said that on that occasion he did not see any signs of any injuries to Mrs. Varley … “

It was said that Mr. O'Connor Spence last saw the following Thursday, where he told him he had had a 'Barney with Sam', was seen as a Black Holdall bag and went to MR O'Connor for a number of nights.
Wood said: “He remembered that he was with the suspect when he bought a phone on the market. He also remembered that he saw that the suspect had some cuts and scratches on his face; But Mr. O'Connor didn't think anything about that anymore. '
Spence had also borrowed a few trainers from Mr. O'Connor, who noticed that one of his toes was 'swollen like a cooked egg'.
Wood said that Spence's trainers were being restored and turned out to have blood color that corresponded to Sam's DNA profile.
He said that the prosecutor anticipates Mr. Spence that he was not present when Sam was attacked.
The process continues.
