A couple was found dead under mysterious circumstances inside the bathroom of their flat in Indirapuram on Friday night. The police said the autopsy report of Neeraj Singhania, 37, and his wife Ruchi, 35, could not ascertain how they died.

Since the couple had no injury marks on their bodies, the police have sent their viscera samples to a forensic lab in Agra. “We have asked the lab to expedite the delivery of their report; it will take around 20-25 days,” said the station house officer at Indirapuram police station Samir Malik, according to The Indian Express.

A first information report has been filed. “We have not received any complaint from the family. The family is in shock. We will record their statements soon,” said Malik.

The couple was found lying on the bathroom floor around 9.30 pm after they had celebrated Holi with their family. The family members broke open the door when the couple did not answer their repeated knocks. “They were rushed to Max Hospital where they were declared brought dead,” said Malik.

The police told The Times of India that they found strips of blood pressure tablets around the bodies.

A family friend, however, debunked theories of suicide. The friend told The Indian Express that the gas geyser in the bathroom was defunct. “There must have been a problem with the electricity or gas being released from the geyser… The couple were very happy with each other… these claims of foul play or suicide are false,” the family friend told the daily.

Indirapuram Circle Officer Rakesh Kumar Mishra said there were no indications of any electrocution, suffocation or any gas formation inside the bathroom due to any electronic appliance such as geyser. “It is strange that none of them survived and could not raise any alarm before they died together,” he told the Hindustan Times.

Neeraj Singhania worked as a deputy general manager with a reputed company while his wife was a professional with a Noida-based firm. The couple has a five-year-old daughter.
