A year after the passing of Kanye West’s mother, Dr. Donda West, an investigation has begun as a nephew may be responsible for her untimely death.

According to People, Stephan Scoggins, a registered nurse, was watching over his aunt during post-surgery in November 2007. Caring for her alongside Ye’s assisant and a friend, Scoggins reportedly left Donda’s bedside to attend a friend’s babyshower immediately following her operation the day before.

She passed away the same evening and investigators are currently pursuing Scoggins to find out how large of a role his absence had on her death. California’s Department of Consumer Affairs is reportedly issuing subpoenas requesting involved persons “to testify in the matter of the investigation of Stephan Scoggins,” according to People.

Despite doctor’s requests that she stay hospitalized after surgery, an autopsy report shows West’s intent to return home.

“[Donda] opted to return to her home for care,” it reads. “Even though she was advised that she receive post-operative care at another facility.”

If Scoggins is held responsible for West’s passing, he could lose his nursing license.
