yep, as a reminder again:
In Facebook comment posted by Graves' girlfriend about a week after he disappeared, she wrote: "He suffers from depression and (bipolar) disorder and I think had a manic episode or psychosis or something."
According to Bach and others close to Graves, at times he has battled with alcohol and substance abuse, and has been treated for bipolar disorder.
Farley said her brother stopped taking his prescribed bipolar medication about two months before his disappearance, because it made him feel overly lethargic.
Another friend, James Tierney, who attended the festival, said Graves wouldn't likely join Twelve Tribes, a Christian group that condemns alcohol and drug use.
Farley said her brother identified as an atheist.
Tierney said Graves talked regularly about his desire to grow marijuana, and believes he may have gone out west to work on a marijuana farm.
Richard Mobley, the father of Graves' girlfriend, who lived in the same house as Graves for a year and a half, says Graves insinuated he wouldn't be returning after the festival.
"He walked away with a plan in mind," Mobley said. "I think he purposely did it to make people think he was dead."
