It is not completely unheard of from time to time for children to kill. But what is far less common is a child serial killer with multiple victims.
Born in 1998 in the village of Mushahar in Bihar, India, Amarjeet Sada is believed to have murdered three people, including family members, by the time he was eight years old in separate incidents between 2006 and 2007.
The sadistic youth reportedly killed his first victim when he was aged just seven and to date he holds the infamous title of being the world's youngest serial killer.
