Even as Central Bureau of Investigation (CBI) informed the Kerala High Court that it cannot take over the probe into the suspicious death of actor Kalabhavan Mani, the medical board informed the court that Mani died of methyl alcohol poisoning. The state government had asked the CBI to take over investigation after actor's family members alleged foul play behind his death. 

The CBI counsel submitted before the court that it was in no position to investigate the case as it is facing a dearth of staff. The state informed the court that the police did not find anything suspicious to assume that the death of actor as homicide. 

Meanwhile, the report submitted by the medical board, constituted by the state government, pointed out that the actor died of alcohol poisoning. It also pointed out the absence of drugs, volatile and metallic poison, alkaloids and pesticides in the viscera of the actor. 

The board, consisting of ten doctors, had examined the postmortem certificate, chemical analysis certificate, examination report of viscera and blood samples, report from the Central Forensic Science Laboratory (CFSL), Hyderabad, histopathology report from Government Medical College, Thrissur and toxicology report from Amritha Institute of Medical Sciences and Research Centre, Kochi. 

The CFSL report had ruled out the presence of pesticides in the viscera samples while Regional Chemical Examiner's Laboratory at Kakkanad had found the presence of pesticide- chlorpyrifos. Following this, blood sample, gastric and viscera aspirates, and urine were sent for detailed examination in CFSL. Detailed examinations revealed the presence of only ethyl and methyl alcohol.

Post-mortem report had mentioned that the actor was suffering from liver cirrhosis, tuberculosis, jaundice, kidney dysfunction and type two diabetes mellitus. It is yet to be ascertained whether the combined effect of these medical conditions resulted in the death of the actor.
