  • Officers broke open the apartment door Tuesday and found the bodies
  • The family was last seen Sept. 21

A couple and their three-year-old son were found dead at their apartment in London allegedly after lockdown arguments.

Police arrived at their apartment Monday for welfare check after one of the couple’s relatives raised concerns. The couple, however, did not open the door. The following day, the officers broke open the door and found the bodies of 42-year-old Kuha Raj Sithamparanathan, his wife 36-year-old Poorna Kaameshwari Sivaraj and their son Kailash Kuha Raj. Police believe that the woman and the child had been dead for sometime and the man stabbed himself when the officers broke open the door.

"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," Detective Chief Inspector Simon Harding said, Sky News reported.

"Our initial enquiries have established that Poorna and Kailash had not been seen or heard from for some time, perhaps since around the 21 September. We know the family often walked their dog, a poodle cross breed, in and around the local area and I would ask anyone who saw them at any time in the last month to contact police so we can begin to build a full picture of their lives," he added.

Meanwhile, neighbors told the Sun that the couple was fighting a lot during the lockdown.

"Things got really bad between them, especially during the lockdown. They are one of the few couples with a young child in our block and you could hear the screaming at each other, sometimes for very long periods," an unidentified neighbor told the outlet.

Meanwhile, calling the incident "horrific," officer Peter Gardner told BBC, "This horrific incident has understandably caused enormous shock and concern among local residents and across the borough. All our thoughts are with the family and friends of those affected. Local residents can expect to see officers at the scene and patrolling the local area to provide reassurance, and if they have any concerns, I would urge them to speak to our officers."

Investigation into the case is ongoing.

Lockdown has affected the mental health of people. Studies have found high levels of depression, anticipatory stress and anxiety among people. During challenging times, the best way to stay positive is by looking after yourself and doing things that relax you, including watching movies or reading books or maybe even having an exercise routine.
