London: The schools attended by the two young Indian-origin girls found dead with their lab technician mother in a suspected chemical poisoning incident in north-west London, are planning a permanent memorial for them.
Prisha, 4, and Jasmine, 9, were found dead at their home in Ruislip with mother Heena Solanki, 34, last Friday.
Prisha was a pupil at Whiteheath Infant and Nursery School in Ladygate Lane while her older sister was a pupil at Whiteheath Junior School, Whiteheath Avenue - both in Ruislip.
"We are deeply saddened by the loss of two of our pupils in such tragic circumstances. Jasmine and Prisha were popular pupils who will be greatly missed by everyone at the schools," Christine Weaving, headteacher of the infant school, and Barry Harmer, her counterpart at the junior school, said in a joint statement.
"We are supporting our children at this difficult time and as part of this will be encouraging them to share their memories and be involved in the creation of something permanent to remember the children," the statement said.
Scotland Yard`s Homicide and Serious Crime Command officers remain at the house as their investigations into the "unexplained" deaths continue.
They fear Heena, who worked at a local secondary school laboratory, may have used her expertise to create a fatal chemical concoction and are not believed to be looking for anyone else in connection with the incident.
"Inquiries continue to establish the full circumstances. We are awaiting a post-mortem, which will take place in due course," a Metropolitan police spokesperson said.
Heena`s husband, 42-year-old Kalpesh Solanki, was not at the five-bedroom family home they shared with his parents during the incident last week.
His parents, 71-year-old Chaganlal and 61-year-old Kalavati Solanki, were reportedly on holiday in Greece and have now returned to the UK to join their son.
Heena, originally from Surat, was set to start a new job in London next month and according to neighbours showed no signs of experiencing any problems. However, some have indicated "rumours" that she may have been suffering from depression.
The Met police have refused to comment on Heena`s mental state in the lead up to the deaths, until the results of a post-mortem are available later this week.
The theory being explored is that the trio may have died as a result of either inhaling or ingesting a deadly poison.
