Woman stabbed in her £4,000,000 mansion had been to ‘murder mystery party’

The family of a woman found stabbed to death at her £4 million mansion near Hyde Park have revealed she ‘suddenly’ left a murder mystery party shortly before vanishing.

Relatives of Kamonnan Thiamphanit, 27, said they also found ‘unusual’ searches for violent rap music on her iPad and YouTube in the five hours either side of her disappearance.

Her boyfriend Chris Zeng, 27, uncovered the list of songs with lyrics about knife and gun violence which she ‘would never listen to’ which were played between of 2.38am and 7.26am on April 6.

Two days later police found the body of Kamonnan, a Chinese Hong Kong and Thai dual national who was also known as Angela, after forcing their way into her home.

Detective investigating her murder have begun extradition proceedings after her suspected killer – who has not been publicly identified – fled the country.

Angela’s Google Maps app shows the route she took back to her home in Bayswater from a friend’s flat in Aldgate East at 3.39am, according to The Times which has seen her search history.

Friends said she had left their fortnightly ‘murder mystery board game’ at around 4am.

Kevin Xia, 22, who hosted the gathering, told the newspaper she ‘seemed more distracted than usual’.

‘I remember thinking she wasn’t playing the game like usual in the last half an hour [because] she was constantly texting someone,’ he said.

They did not ask who she was messaging, he added, but they recalled Angela saying she would be ‘booking an Uber home because there was an emergency’.

Detectives have said they believe it is ‘likely’ she was killed by someone she knew.

Her family claims she allowed a stranger to rent her home for around £30,000 which was supposed to be paid into her bank on the evening of April 5, The Times reports.

Mr Zeng, who is based in Singapore and was in a long-distance relationship with Angela, said she told him and her mother about the offer.

Speaking to MailOnline previously, he said: ‘Angela told me that this man was coming to see the property on Friday 5 April. She did not tell me his name, nationality or any other details about him. 

‘All she said was that he seemed to be very rich, had flown to London on a private jet and had a child. That was it.’

Angela called Mr Zeng afterwards to say the mystery man was ‘very happy’ with the house and had expressed an interest in renting it for up to three months, potentially earning her £90,000.

But she also said they agreed to bypass Airbnb and not make the payment through the company, which charges hosts around 3-5% commission.

Angela’s mother Fiona Fu, who lives in Hong Kong, said: ‘The man suggested that he and Angela just deal with each other directly. 

‘He said he would bank transfer her £30,000 the following day and moved in straight away.

‘She wasn’t worried about anything and there was nothing about this man that made her suspicious.’

Mr Zeng said he started to worry when Angela decided to leave her games night early and stopped replying to messages.

He then got a message late on Saturday reading ‘Sorry for delay’.

‘We never communicated in English, only Chinese,’ he continued.

‘As soon as I saw that message, I knew that it wasn’t Angela and that something had happened to her.’

The Metropolitan Police has referred itself to the Independent Office for Police Conduct (IOPC) following the murder.

On Sunday, April 7, officers were contacted twice by Angela’s friends who were concerned about her welfare.

This was graded as a medium-risk missing person inquiry before officers forced entry and discovered her body the following morning.
