The accused, Dr Chandra Vibhas Sahu, a surgeon at the DDU hospital, West Delhi was a batch topper in his masters course and is alleged to have had a history of behaving violently towards his 27-year-old wife.
The victim, Supriya Tussar had completed her MBA from Rajasthan and had done BTech from Hyderabad. She had recently got a job offer from an IT major, who offered to pay her Rs 85, 000. But her husband objected to her working.
The accused after his arrest told the police that he was "physically and mentally incompatible" with his wife Supriya. Though the real cause of the provocation remains unknown.
Additional CP (west) V Renganathan however said that Sahu might have been plotting to kill his wife for sometime.
Reports also suggest that the local Hari Nagar police station also received several calls in the past about the couple's fight in their 10 month old marriage citing that Sahu often got violent during their fights.
The police revealed that Sahu after killing his wife stuffed her in a canvas bag and then drove non-stop to Bihar. Suspecting that he was being followed by his in-laws, the accused however changed his plans and then drove to Haria in rural Allahabad.
Sahu then dumped the body in the Ganga thinking that the body would be washed away.
"But the place where he dropped her body was a swamp caused by flooding. When the water receded, the UP cops recovered the body," said an investigator.
In Feb 2011, Sahu threw her out of the house, on her return in Jul, he forced Supriya to spend a week in a mental asylum to prove that she was mad.
