The suspects, according to the police, are drug peddlers and one of them, is a "sexual pervert who had abused women and men in the past," in the same isolated marshy area, where the tourist's body was found.
Senior police officials have confirmed to NDTV that "the postmortem report didn't reveal much because the body was badly decomposed." However, the police sources say they have been able to confirm that the accused had the motive of rape and murder.
The tourist's funeral will be held today in Thiruvananthapuram.
The tourist had arrived in Kerala for ayurvedic treatment for post traumatic depression. On February 21, she left the treatment centre, without informing her sister and couldn't be traced after that. Her sister had earlier alleged delayed police action led to loss of critical time in tracing her sister. But now she says she is satisfied with the police investigation.
"Senior police officer Manoj Abraham has been in regular touch with me. I know they are doing their best give us justice. I am satisfied with what they are doing, and don't want to delve into the past," Ilze told the media.
