The Los Angeles County Medical Examiners' office says Lisa Marie Presley, the only child of the iconic musician Elvis Presley, died earlier this year as a result of “a small bowel obstruction.”

Presley, who was also a musician, died January 12th, just two days after she attended the Golden Globes where she saw Austin Butler take home the Best Actor award for his portrayal of her father in the film Elvis.

The obstruction that Presley had “is a known long-term complication” of bariatric weight loss surgery, the medical examiner’s office said. Her surgery was performed “years ago,” according to the report.

The medical examiner’s report also said Presley had "therapeutic levels" of oxycodone and other medicine in her system but added that they were not seen as contributing factors to her death.

Presley was once married to Michael Jackson, another iconic performer.
