According to police sources, doctors have not been able to identify the reason behind Raymond's death, and has even indicated that the deep gashes found on the body could have developed due to decomposition and may not actually be injury marks.
A senior police official said the initial autopsy report is inconclusive and they would have to wait for the viscera report and other forensic reports to identify the cause of death.
"We have searched Bhogal and surrounding areas but could not find such a bag. The bag must have been bought from the area where he was killed. If we can find that, it can help take the investigation forward," a police official said.
Police has found that Raymond had come to Delhi on April 24 and checked into a hotel in central Delhi with the help of a tout he met at Nizamuddin Railway Station. He had his lunch in the afternoon near the hotel.
