San Luis Obispo County District 3 Supervisor Adam Hill was found dead at his home in Pismo Beach on Thursday.
In early July, Hill announced that he was seeking specialized treatment for depression and encouraged others who were struggling to reach out for help.
In March, Hill was hospitalized and later stated that he had attempted suicide.
"In the weeks leading up to Election Day, I fell into a bad episode of depression, culminating in an attempt to end my life," he said.
Hill won the March 3 supervisorial race against Stacy Korsgaden by just 587 votes following a heated campaign.
On the same day that Hill was hospitalized, the FBI served a search warrant at the San Luis Obispo County Government Center. Hill said at the time that he could not comment on the pending and confidential investigation but that "we are cooperating fully with their inquiries."
The FBI also would not comment on the investigation.
In April, Hill resigned his position as Chair of the Board of Supervisors but resumed his duties as District 3 Supervisor.
The County of San Luis Obispo released the following statement about Hill's death Thursday evening:
It is with sadness that we have been informed that Supervisor Adam Hill has passed away. This is shocking and tremendously painful news. While we are unaware of the details at this time, we ask everyone to let the proper authorities do their jobs and investigate. Please respect his family's privacy at this time.
