He dismissed some media reports that Jolly, the main accused, had exhibited suicidal tendencies and said she had been hospitalised after complaining of uneasiness.
"We came to know that she has been hospitalised due to some uneasiness. I enquired whether she had exhibited any suicidal tendencies, but learnt that there was nothing of the sort," Behra said.
Meanwhile, a police department release said they would approach a Court for permission to conduct a 'Trace Analysis' on the exhumed bodies at the best laboratory in the country.
"If that is not possible, we will seek permission to approach the best labs abroad. We cannot say whether there are more suspects in the case," the release said.

The two other accused--M S Mathew (44), is a close friend of Jolly and Prajikumar, (48) had allegedly supplied cyanide to Mathew who handed it over to Jolly.
Jolly was arrested only in the case relating to the death of her husband in 2011 due to the presence of cyanide mentioned in his post-mortem report.
The SIT is probing the case after receiving a complaint from Roy's US based brother, Rojo, over the six deaths between 2002-20.
Police sources said they have also decided to issue a notice to Rojo to appear before them for questioning as and when necessary.
