The star - whose uncle was country singer John Denver - was also in the 2017 documentary, Cleanin' Up the Town: Remembering Ghostbusters.

Henry committed suicide by hanging himself, according to the medical examiner.

William found him in his apartment and tried to save his life by cutting him down but he was too late, the site claimed.

Hank was battling schizoaffective disorder, which is a combination of bipolar disorder and schizophrenia.

In a online tribute William said: 'It is with great sadness that I announce the passing of my twin brother, Hank. On Wednesday, June 14th, 2017, Henry John Deutschendorf II lost his battle with schizoaffective disorder.

'Many people do not know much about Hank. Some knew him as Baby Oscar in Ghostbusters 2 or John Denver’s nephew. Others knew him as a brother, son, martial artist, teacher, uncle, or friend.

'What people do not know about Hank was that he suffered from schizoaffective disorder. It is a chronic mental health condition which is a combination of bipolar disorder and schizophrenia.

'He experienced hallucinations, delusions, depression, and mania. It is a very severe mental illness that usually requires a lifetime of treatment. It is not well studied, so the treatment is largely an estimation based on schizophrenia and bipolar treatments.'

He added: 'Hank would have good days and bad days. He didn't take a real sick day for the past nine years that I can remember.

His love: In William's tribute he also mentioned the star had a 'loving girlfriend'; here they are seen in a Facebook photo

'Sometimes he would lie and say he was sick because he felt guilty, but I knew he really just couldn’t stand another day on the mat with his voices.

'He never took a real vacation, other than a few trips with his loving girlfriend. Any day he stayed home was because of his voices and delusions. Sometimes he stayed home because he was manic and couldn’t sleep. Other times he was so depressed he could not leave his home.'

Hank and William ran a martial arts school in the San Diego area.
