Jack Wagner's son, Harrison, has died. He was only 27.

Harrison, the son of "General Hospital" stars' Jack and Kristina, died on Monday in a parking lot in Los Angeles.

A spokesperson for the Los Angeles County Department of Medical Examiner-Coroner confirmed the news to Page Six, saying that he was initially found in a parking lot before a doctor formally pronounced his death in North Hollywood at 5:14 a.m.

As of press time, Harrison Wagner's cause and manner of death remain under investigation.

His father refused to give a statement, but ET Online confirmed that the authorities had already scheduled his autopsy.

An investigator has also been appointed to look into the young man's case.

While the story about how he died is still unknown, it has been disclosed that he previously battled addiction. Still, it is unclear if it had something to do with his death.

For what it's worth, he went missing for a week in July 2016 after a relapse.

"I'm going to ask those who want to share their fears, addictions & struggles to do so w me via Twitter. We can face them 2gether, I'll start," the actor shared on Twitter at the time. "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."

Before Harrison's death, he was still able to share his last post featuring a photo of him sitting on a bench while listening to music.

He was Jack and Kristina's youngest son. The celebrity couple also shares 31-year-old Peter Wagner together.
