'He died vehemently in his workplace" - please clarify edit

I am intrigued by the sentence "He died vehemently in his workplace at the age of fifty-four". It appears it may be a translation directly from a foreign language by someone who did not have English as mother tongue. Clarification would be appreciated - is it meaning to say he died violently or suddenly and from what cause? Clicking the citation merely gets a 'page not found' message.Cloptonson (talk) 06:19, 2 August 2021 (UTC)Reply
