Not much has been publicized about the circumstances of Robin Williams' suicide last year, until now. Reports have been surfacing claiming to shed more light into the "Mrs. Doubtfire" actor's demise.

According to In Touch Magazine, there are purportedly new evidence that suggests Robin Williams' death may not have been suicide. The actor's death was allegedly reopened and two investigators assigned to the case reportedly think that there could be foul play involved.

"One private investigator, who requested anonymity, has visited Robin's home, the one he shared with his wife of three years, Susan Schneider, says that he has been to the home in Tilburn, California on several occasions," Celeb Dirty Laundry wrote.

The investigator, allegedly promised that he will look into the case that he described as "fascinating but tragic."

"The second private investigator, a former police chief named Sue Dietrich Nance, believes there is much more evidence that has not been revealed about Robin Williams' death and that there is much, much more to the story," the webite continued. "Is his widow Susan Schneider at the root of covering up evidence?"

Speculations that Robin Williams death was not a suicide may go against previous reports claiming that the comedian was purportedly suffering from depression. A year after the actor's untimely death, a new report surfaced suggesting that Robin Williams allegedly left suicide notes before his demise last year.

Just this month, it has been reported that Robin Williams' suicide notes were allegedly found after his death, but the notes were not immediately publicized.

"Williams often wrote little notes to himself as a kind of therapy," Globe Magazine reported.

The article added, "Robin scribbled words on pieces of paper and left them all over the place. On their own, they really didn't make much sense. But when you look at them as a whole in light of the suicide, Robin was clearly reaching the point where he couldn't take the pain and anguish of his life any longer."

According to the report, Robin Williams' first suicide said "I'm done with that." The second note reportedly said, "Time to go," while the last note said "No more to come."
