A convicted rapist texted a friend saying he had been 'hearing voices' talking about him and warned police he had a machete before he stabbed his lover to death, the Old Bailey heard.
Taye Francis, 40, knifed Khloemae Loy, 23, through her neck at the Holiday Inn Express near the O2 arena on the Greenwich Peninsula, south-east London on July 5 last year.
He then fell 50 feet as he tried to escape from a fifth-storey window, suffering serious injuries.
Police and paramedics raced to the £59-a-night 3-star hotel but Ms Loy died at the scene.
Jurors heard Francis abused steroids and was repeatedly violent to Ms Loy whose parents had begged her to leave him.
On May 6, Francis texted a friend saying he had been 'hearing voices' talking about him.
Eight days later, police officers visited Francis at his flat, where he told them he had a machete and had installed CCTV in his kitchen.

Police initially visited Francis's Kingston address on May 7, to monitor him because he is on the sex offenders register due to a rape conviction in 2002.
He shouted at the police saying: 'What the f-k do you want'.
'He was puffing his chest out and trying to intimidate officers,' said prosecutor Kate Lumsdon.
Francis has 'bad PTSD' and anxiety and was on medication because of his mental health problems.
On 10 May his flatmate texted him saying: 'The new slogan is no longer stay at home it will be stay alert.
'They don't need to say 'stay alert' to me. I'm hyper alert to the police and any dodgy character,' he responded. 'It's making me paranoid.'
He contacted the Jigsaw Team - responsible for liaising with sex offenders in the community - on May 11 saying: 'I believe my neighbours have found out about my rape conviction, I believe they're planning an attack.

'I must protect myself and my girlfriend living with me.'
