I went hunting backward both -17 and -34 months from 4/9/21.

Found Anthony Bourdain at -34 months on 6/8/18

Anthony Bourdain, 61, American chef, author and television host (No Reservations, Parts Unknown, The Layover), four-time Emmy winner, suicide by hanging.[159]

Could not identify anyone of obvious significance at -17 months, but found interesting Pope Francis Argentinian Jesuit “influencer” died on 11-27-2019

Scannone was an instructor in the Jesuit Seminary of San Miguel in Argentina. There, he was one of the main teachers of Jorge Bergoglio, who later became Pope Francis. Arguably, few theologians influenced Francis as much as Scannone.[5][6]

Probably NOT a “natural death” as Pope Francis has incentive to cover his tracks and enemies of Pope have incentive to takeout his mentors.
