Mary Jo Campbell, the mother of Kris Jenner, dies aged 91. Reports say her cause of death is revealed nearly two weeks after her death, despite earlier coverage focusing on her passing and her family connection. Multiple outlets state that the disclosure comes after a delay of about twelve days. The reporting does not indicate any change in the circumstances of her death beyond the later publication of the cause. The articles describe her as Kris Jenner’s mother and note the timing of the announcement relative to her death. No additional details about the specific cause of death are included in the provided excerpts, and the accounts do not describe any competing explanations. Overall, the information shared across sources centers on two points: Campbell’s death at age 91 and the subsequent release of information about the cause nearly two weeks later.
