The post-mortem examination of software company owner Naveen Kumar that was conducted on Monday could not reveal the exact of his death.
To shed light on what may caused his death, UT police have now sent Kumar's viscera to the Central Forensic Science Laboratory (CFSL).
Naveen's decomposed body was found floating in the waters of a canal in Barwala near Hisar on Saturday evening. He had gone missing from his house on May 10, two days before his marriage.
A police source said the exact cause of Naveen's death was not clear in the report of the post-mortem examination.
UT police crime branch inspector Ranjodh Singh said the viscera have been sent to CFSL. "The report will make it clear what was the exact cause of his death."
He said the body was highly decomposed as it appeared to have been floating in the canal for several days. There were no visible external marks on the body. Naveen's motorcycle was recovered on May 12, two days after he had gone missing. Family members suspect that four persons who used to work for Naveen's company in Sector 47 may be behind the death as they had been sacked a few days before Naveen had one missing.
But, so far, nothing incriminating has come out against anyone in the case.
