A septuagenarian man was found dead after falling off his multi-storey rooftop, and his sixty-three-year old wife was found dead with her throat slit in her room at a residential complex in south Kolkata on Tuesday, police said.

The police, during an investigation, learned that Amulya Samadhar (73) jumped to death Monday night after killing his sick wife, Gita Samadhar and locked his flat at Valmiki Abasan at Nonadanga in the Anadaour area.

The deceased man took his wife to a physician Monday evening and was told to get her admitted.

They returned home and then committed the crime in frustration.

The wife had been suffering for a decade.

Police said the husband first slit Gita's throat with a knife and pressed a pillow over her face to end her life.

Then he locked the flat from outside and went atop the roof to jump from the 4th floor building around 2130 hours on Monday. The bodies were taken for postmortem.
