He then proposed marriage. He wanted no dowry and urged the women to elope with him to faraway towns after swearing them to secrecy.
Mohan allegedly had 12 aliases, and mostly chose a surname that indicated the same caste as that of his victim. After taking a room in a small lodge, he would have sex with his victim on the night before the so-called wedding, and then give her cyanide.
One of Mohan's victims, Sunanda Poojary, even took a bank loan of Rs 25,000 before eloping with him.
Finally, with the help of Anitha's cell phone records, the police zeroed in on Mohan, who had used the phone to get in touch with some of his other victims.
