On May 17, 2008, Aarushi Talwar, a 14-year-old school student and daughter of a dentist couple, was found dead with her throat slit in the bedroom of her flat in Jal Vayu Vihar in Noida. On the next day, domestic help Hemraj's body found on terrace of Talwar's residence. Former domestic help Vishnu Sharma was named as a suspect.
The day after the girl's murder, a family friend opened a locked terrace door and found the missing servant with his throat slit as well. Police had missed finding the body in their initial investigation. The initial autopsy report of Aarushi rules out sexual assault. Police said a surgical instrument was used to slit the throats of Aarushi and Hemraj.
Vijay Mondal, the domestic help of one of Talwar's neighbours was also later arrested by the CBI. After spending 50 days in jail, Rajesh Talwar was released. The arrest followed polygraph test and narco analysis tests.
No murder weapon has been found. Police injected suspects with truth serum -- the anesthetizing drug thiopental sodium has become increasingly common in India in the past five years despite criticism from lawyers and human rights groups. Woozy suspects are supposed to find it harder to lie or deflect questions.
Rajesh Talwar set free by local court following CBI failing to get evidence against him. Vijay Mandal, the domestic help of Talwars' neighbour arrested.
Vijay Mandal released on bail. Krishna and Raj Kumar released on bail. CBI announces a cash reward of Rs 100,000 for clues leading to recovery of weapon of offence and mobile phones of Aarushi and Hemraj.
The CBI closed the Aarushi Talwar murder case, more than two-and-a-half years after the teenager was murdered. The closure report which was filed at a Ghaziabad court meant that all the three suspects in the case - Raj Kumar, Vijay Mandal and Krishna - will be set free. They are out on bail now.
The Talwar family decided to file an appeal against the closure report. They said they were devastated and shocked with the news. Talwars' lawyers submitted an application requesting the court to allow them to oppose the CBI closure report.
The Uttar Pradesh police arrested Aarushi's father Rajesh Talwar on May 23, claiming they suspected this to be a case of honour killing.
It was the CBI who said they had no evidence that the father, who all along protested his innocence, was involved. The suspect is now an assistant of the father and two neighbourhood domestic helpers, according to the CBI.
A new team was constituted by the CBI to look into the Aarushi case. The new team could only recover Aarushi's mobile, which was put through forensic test but not much could be recovered. Raj Kumar and Krishna leave for Nepal.
