From the article above:

Vijay Mehta, a fixture in the Indian American community in Texas, told India-West he too believed something suspicious was happening with the couple. “Indian men can be very jerky. Even within seven days he could have said or done something to completely set her off,” he said, adding, “It amazes me, how, within seven days, she was smart enough to plan all this.”
God knows what actually happened?
But she should have thought of a better way to dispose him off if she really wanted to get rid of him.
