Boy, 3, was found dead with mum and dad in ‘murder-suicide’ at home

The father is believed to have fatally injured himself when police forced entry into their flat.

A mother and her three-year-old son who were killed in a suspected murder-suicide are believed to have been dead ‘for some time’ before they were found.

The bodies of Poorna Kaameshwari Sivaraj, 36, and son Kailash Kuha Raj were discovered by police at the family’s flat in Brentford, west London, shortly before 1am on Tuesday.

Poorna’s husband and Kailash’s dad, Kuha Raj Sithamparanathan, 42, was also pronounced dead at the scene.

He is believed to have taken his own life when officers forced their way into the flat, said Met Police.

It is believed their cockapoo dog was also killed in the incident, reported MailOnline.

Police said although they are in the ‘infancy’ of the investigation, they believe the mother and son may have been dead for several days, as neither had been seen since September 21.

Officers had initially been called late on Sunday by a family member raising concerns about the welfare of Poorna.

They went to the address ‘several times’ in the early hours of Monday but did not get a reply. After speaking with neighbours they became increasingly concerned and decided to force entry.

A referral has been made to the police watchdog, the Independent Office for Police Conduct, as it is believed the father fatally injured himself when officers forced their way in.

Next of kin have been informed and post-mortem examinations will take place on Thursday.

Neighbours expressed their shock at the devastating news and said the couple, who married in 2015 in Kuala Lumpur, were ‘lovely’ and ‘very friendly’.

Jamila, who lives in a neighbouring block, told MailOnline: ‘It’s tragic. They loved their dog and I’d see them all the time taking him out for walks. They were a lovely family and none of this makes any sense.

‘The officers told me that there was blood all over the flat and that the dog had also been killed.’

However, one resident on the fifth floor said they had heard the couple arguing ‘a lot’ during lockdown.

They said: ‘I could hear her screaming at her husband, telling him to take his medicine. Then on another occasion, he threw them out of the window, and I looked down and could see them on the ground.’

Sheri Diba, who has lived in the building for seven years, said she regularly saw the family walking their dog but had not seen them for months.

The mother-of-one said: ‘I’ve always seen them in the lift. They were very friendly. They said “Hi, how are you?” I always saw them together going for walks.

‘I feel really bad because they were very friendly, nice people.’

Detective Chief Inspector Simon Harding said: ‘Although we are in the infancy of this investigation, it appears that Poorna and Kailash had been dead for some time.

‘This is a murder investigation and my team will work diligently to establish the sequence of events that led to their murders and the death of Kuha Raj Sithamparanathan.

‘Our initial enquiries have established that Poorna and Kailash had not been seen or heard from for some time, perhaps since around September 21.’

He said the family had often been seen walking their poodle cross-breed in the local area and asked anyone who had seen them in the past month to contact police ‘so we can begin to build a full picture of their lives’.

‘Words cannot sufficiently sum up the devastation that this horrific incident will have on the families of those involved,’ he added.
