Autopsy report released by the San Mateo county coroner's office that terms the death as an 'unforunate accident' says the cause of death was 'drowning'.
According to the report, Motwani's blood alcohol level was at 0.26 per cent as opposed to the US permissible driving level of 0.08. Since each individual has different tolerance level to alcohol, it can't be surely said that the death was cause due to alcohol. But this is seen as a contributing factor to the accident.
"It is difficult to know what effect a given alcohol level will have on a person because tolerance varies from individual to individual," San Mateo County Coroner, Robert Foucrault said, adding that it was a 'contributing factor'.
Foucrault also informed that there will not be any more further investigation done on this case.
