A man accused of murdering a mother-of-three and setting her house on fire has told a court he was left scared for his life when he interrupted the real killer.
Brendan Rowan-Davies is accused of torturing Kelly-Anne Case, 27, before cutting her throat at her home in Grange Crescent, Gosport, on 30 July.
The 29-year-old told a jury he had attempted to film her and his friend having sex the previous night.
He denies murder and arson.
Giving evidence at Winchester Crown Court, Mr Rowan-Davies told the jury an unknown man held a knife to his throat as he walked into the victim’s bedroom.
He said he had known the victim for some time and spent an evening with her and another friend the night before her death, drinking vodka and taking cocaine.
Under cross-examination he said he told Ms Case he “fancied” her that night but that she had laughed it off.
Prosecutor William Mousley QC asked: “How did it make you feel when she laughed?”
He replied: “I was used to it,” adding it was “normal”.
The jury was told his friend went to bed with Ms Case that evening and the defendant attempted to covertly film them having sex through a gap in the door.
He told the court he went back to Ms Case’s house the following day to collect some tobacco he had left behind but nobody answered the door.
The jury heard he found the back door open and went upstairs where he saw Ms Case lying dead in her bed.
“Someone put a knife to my throat,” Mr Rowan-Davies told the court, adding: “I was scared for my life.”
The defendant, of Haslar Road, Gosport, said the alleged perpetrator told him he would kill him and his family if he ever said anything about it, so he had kept quiet as he was “petrified and didn’t know what to do”.
He then burned the clothes he was wearing so police “wouldn’t think it was me”, he added.
Earlier, jurors were told Mr Rowan-Davies was convicted of a burglary in 2017, in which he broke into a house where a mother and her two young daughters were in bed.
Prosecutor Alex Kettle-Williams said he had claimed he broke into the house out of concern because he believed he saw intruders inside.
The trial continues.
