Mohan Kumar
Number of Victims: 20.

Method of Murder: Cyanide poisoning.

Mohan Kumar alias Ananda was a physical education teacher in Bantwal Taluk of Karnataka. He confessed of killing 20 young girls over a period of 5 years. His modus operandi was to lure unmarried young girls into marrying him. The next day after marriage, he would kill them by giving them cyanide stating it was an anti-pregnancy pill. After killing his victims, he would abscond with their jewelry. He never came in contact with the victim’s family and so was never a suspect. Police however tracked him down in 2009 using the mobile phone of a victim, which was still being used by him. He is presently incarcerated awaiting trial.
