Serial killer Chandrakant Jha, who would dump headless bodies and torsos of his victims near Tihar Central Jail here during 2006 and 2007 and write letters or make phone calls daring cops to catch him if they could, has been sentenced to spend the rest of his life in prison for the last of three murders that he committed before being arrested.

Though the police have suspected his involvement in other murders from 1998 onward, charges in those cases failed to stick in court. The three sensational murders which hogged headlines in 2006-07 had a similar pattern with decapitated bodies being thrown outside Tihar Jail on October 20, 2006, April 25, 2007, and May 18, 2007. Additional Sessions Judge Kamini Lau had held the 46-year-old former vegetable retailer guilty of all three murders on January 24.

Jha, a father of five minor girls, was sentenced on Monday for the murder of the person whose body was found on May 18. In a letter found along with the body, Jha had send a chilling message to the police that they could expect “more of such gifts” (decapitated bodies) every 15 days henceforth. He was, however, arrested two days later on May 20, 2007.

Terming Jha a “mission-oriented serial killer” whose only motive was to mock and challenge the police for allegedly falsely implicating him in many criminal cases, ASJ Ms. Lau said it was desirable to keep him out of circulation of society.
