Kris Jenner Mom’s Cause of Death Confirmed

New details have come to light regarding Kris Jenner’s mom Mary Jo “MJ” Shannon’s death. 

Less than two weeks after MJ died surrounded by her loved ones, her death certificate, obtained by E! News, confirmed that the 91-year-old’s death was caused by acute cardiopulmonary arrest. 

MJ—who was the grandmother to Jenner’s kids Kourtney Kardashian, 47, Kim Kardashian, 45, Khloe Kardashian, 42, Rob Kardashian, 39, with late ex Robert Kardashian, as well as Kendall Jenner, 30, and Kylie Jenner, 28, with ex Caitlyn Jenner—had other ongoing conditions that contributed to her death including acute respiratory failure and metastatic lung cancer.

The Kardashian matriarch died on July 16 in the hospital, per the certificate, just 10 days shy of her 92nd birthday. 

Following the death of her mom, Kris shared a heartfelt tribute honoring her full life. 

“There are no words that could ever capture what she has meant to me or the heartbreak of having to say goodbye,” Kris wrote in a July 16 Instagram post. “My mom was the heart of our family.”
