There are murderers and then there are serial killers. There's usually some sort of motive behind most homicides but when it comes to serial killers, motive gets replaced by this psychological urge to kill; most often devoid of any logical reason or personal vendetta against the victim. India has had its fair share of serial killers. Most often, they were eventually apprehended, but there are cases where the wrong person was arrested (and then let go) and then there are some cases that still remain unsolved. These cold-blooded Indian serial killers will send shivers down your spine.

10. Stoneman Killer(s) - A mysterious identity that still remains in the shadows

This is one of the most infamous unsolved murders in Indian history. Almost like our own version of Jack the Ripper. In 1989, nine people living in Bombay were killed in a similar fashion - their heads were smashed with a heavy blunt object, prompting a Calcutta newspaper to name the unknown killer, The Stoneman. It is possible that the later murders were copycat murders but there's no way to know that.

11. Akku Yadav - The murderer who got served by karma

Akku Yadav was not a serial killer per se; he was more of a local goon who used to rape and kill women in the area where he ran his business. The 32-year old Yadav was lynched by a mob right outside Nagpur District Court. One of women even hacked his penis off. Total poetic justice right there. When the cops tried to nab people from the mob, every woman in the slum where Yadav operated asked to be arrested. Power of the people FTW!
