Though the DNA tests are preliminary in nature, they have become the talk of the town. On September 5, a close relative of Madhumita told Outlook that the family's suspicions had been confirmed: "We were all awaiting the DNA tests (result). Now that it's come, it's for the CBI to do the needful and arrest the guilty." CBI sources say Tripathi will now have a lot of explaining to do.
The investigating agency has already interrogated him on four occasions. He was quizzed in Delhi and the day the preliminary results came in, his wife Madhumani was being interrogated in Gorakhpur. Probing the 'jealousy' angle, the CBI questioned her about the alleged call she received from Madhumita's Paper Mill Colony house soon after the murder.
