"Deferred means that, after an autopsy, a cause of death has not been determined, and the medical examiner is requesting more investigation into the death, including additional studies," the coroner's office told Fox News Digital. "Once the tests/studies come back, the doctor evaluates the case again and makes the cause of death determination."

Since Harrison's death, his brother and ex-girlfriend have paid tribute via social media. Peter Wagner shared a carousel of photos and captioned the post, "Always with you."

"Seven years, on and off, round and round we loved each other," she wrote. "For better or for worse. In sickness and in health. Sorry, I missed yr calls in the middle of the night these last few days. I miss sleeping in yr pola bear arms, curled up. I miss sending you silly animal videos. I miss you sending gorgeous songs that made me cry.

"I fear for my youngest sons safety. Harrison has struggled w drugs & alcohol just as I did when I was younger. He’s relapsed & is MIA 5days."
