Police in northern Indian state of Uttar Pradesh have not been able to come up with any clinching evidence against a doctor arrested recently for twin murders. The investigations are to be shifted to the federal police now.
Aarushi, a class 9 student of Delhi Public School (Noida) was found dead with her throat slit in her family's Jal Vayu Vihar apartment on May 16. The police initially named domestic help Hemraj as the prime accused but his own dead body was found on the building's terrace the next day.
Aarushi's dentist father Rajesh Talwar was arrested on May 23. The police claimed he killed Aarushi in a fit of rage as he objected to her closeness to Hemraj, but the family has strenously denied the police allegations.
Three days of intense interrogation of the arrested Talwar does not seem to have produced any useful lead.
Even the weapons used in the crime (hammer and scalpel, as per police claims), are yet to be recovered. So is the case with the bloodstained clothes of Talwar or the victims' mobile phones.
"The police haven't recovered anything during his custody. That's why Talwar has been sent to the Dasna Jail," said Senior Prosecution Officer PC Srivastava.
The police could rely on strong circumstantial evidence, if any, to prove their case against Talwar during trial, said legal experts. But the police are not clear about the exact chain of events leading to the murders and more importantly, the motive behind the killings.
Phone call records, circumstantial evidence, interrogation and even scanning of Talwar and Aarushi's computers have not taken the police anywhere near nailing Talwar.
The police have told the court that Talwar is not cooperating and have requested for permission to conduct a narco-analysis test on him. The test could be crucial in deciding how strong the case against Talwar could be in the long run, said criminal lawyer Kamini Jaiswal.
The results of such a test are not applicable in the court in normal circumstances. "Narco test can be used as evidence only if it leads to recovery. The revelations may not be used directly as evidence but can provide key links that could plug gaps in the police's theory," said Jaiswal.
While Talwar could be stonewalling all questions and his family protest his innocence, the fact also remains they are not able to say who else could have had a motive to kill either Aarushi or Hemraj.
Meantime the Central Bureau of Investigation (CBI) is likely to take over the investigations.
