The death certificate also states that Karen had been previously diagnosed with bipolar disorder and was cremated following her March 18 death.
Kris announced her sister's death on Instagram the following day, sharing several unseen photos of the two over the years, including snaps with their mom, MJ, a young Kourtney, and Kris' late husband Robert Kardashian.
Alongside the photos, Kris penned a heartwrenching tribute, which read: "It is with the heaviest heart and deepest sadness that I share that my sister Karen passed away yesterday unexpectedly.

Kris added: "She holds such a huge part of my heart and I cherish every single memory we have together. Karen's passing is a reminder that life is so short and precious and tomorrow is never promised.

"Dear Mommy, I can't believe you're gone. This doesn't even feel real," she began.

Natalie continued: "You were the most kind, sweet, loving, giving, and caring soul. You had the biggest heart. And I don't know how to go on without you. It all happened so quick & I wasn't ready for you to go."
