London:
Indian-origin lab technician Heena Solanki, who was found dead with her two daughters in north-west London earlier this month, had left a note for her husband, an inquest was told.
The hearing into the death of the 34-year-old mother and Jasmine, 9, and Prisha, 4, opened in London yesterday and was adjourned. Police investigations are on in the case.
Scotland Yard investigating officer Sarah McConnell told the brief hearing at West London Coroner's Court that "some sort of chemical mixture in three glass bottles" is being examined in what appears to be a case of chemical poisoning.
"Also present was a note which appears to be from Heena, addressed to her husband," she added.
The officer also told the hearing that it was husband Kalpesh Solanki, 42, who had discovered the bodies when he returned to their family home in Ruislip from work in the evening on April 12.
He had last seen his wife and daughters alive that morning.
Jeremy Chipperfield, the assistant deputy coroner for west London, asked if police were seeking anyone else in connection with the incident to which, McConnell replied, "Not at this time, no."
She added that post-mortem examinations had been conducted last Thursday and the cause of death as well as toxicology results were awaited.
Scotland Yard's Homicide and Serious Crime Command team has been probing the "unexplained" deaths and feared Heena, who worked at a local secondary school laboratory, may have used her expertise to create a poisonous chemical concoction.
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 inquest is expected to delve into the mother's mental state when it resumes at a later date following police investigations.
