The Noida serial murders (also Nithari serial murders, Nithari Kand) occurred in the house of businessman Moninder Singh Pandher in Nithari, India in 2005 and 2006. His servant Surinder Koli was convicted of the five murders and was sentenced to death. Eleven murders remain officially unsolved pending further legal proceedings. Surinder Koli's death sentence was changed to a life sentence by the Supreme Court on 7 September 2014.
In December 2006, two Nithari residents claimed they knew the location of the remains of children who had gone missing in the previous two years: the municipal water tank behind house D5. Both had daughters who were missing, and they suspected Surinder Koli, the domestic help at D5, had something to do with the disappearances. The residents claimed they had been repeatedly ignored by local authorities; therefore, they sought the help of former Resident Welfare Association (RWA) President S C Mishra. That morning, Mishra and the two residents searched the tank drain. One of the residents claimed to have found a decomposed hand, after which they called the police.
Anxious parents of the missing children rushed to Nithari with photographs. Koli, under the alias Satish, later confessed to killing six children and a 20-year-old woman known as "Payal" after sexually assaulting them.
