The autopsy report said she had been complaining of stomach pain earlier in the day. Presley experienced a common complication from a bariatric surgery procedure she had years ago. 

The Mayo Clinic says it is often done when other weight loss methods haven't worked or if a person has a serious medical condition.

In January, Presley had been "transported" to a hospital after sheriff's deputies responded to a "not breathing call" at her home in Calabasas, authorities confirmed to Fox News Digital at the time.

Lieutenant Zeko of the Malibu/Lost Hills Sheriff's Department confirmed officers responded to a call "for a female adult who was not breathing, and the fire department began rendering aid to the patient, and they transported her to a local hospital."

Presley, a singer-songwriter, was the only daughter of Elvis and Priscilla Presley. She also had a half brother, Navarone Garibaldi, from Priscilla's 20-year relationship with Marco Garibaldi.

"Although the media identified such a plea as a lawsuit, I want to make clear that there was never any lawsuit filed against my beloved granddaughter. As a family, we are pleased that we resolved this together."

Priscilla, 77, had challenged an amendment allegedly made by Lisa Marie in 2016 that replaced her business manager and mother as beneficiaries with her oldest children, according to the Los Angeles Times.

Lisa Marie's son, Benjamin Keough, died by suicide in 2020, making Riley the sole beneficiary.
