The soap opera actor died on Sept. 15 at age 43, following a "history of bipolar disorder and depression," per the autopsy report obtained by PEOPLE from the Travis County Medical Examiner in Texas
Billy Miller’s cause of death has been determined.
According to the autopsy report obtained by PEOPLE from the Travis County Medical Examiner, the Daytime Emmy Award winner was found dead in his bathtub “with an apparent gunshot wound to the head.”
Authorities found “a revolver chambered for .410 shotgun shells” in the actor’s right hand as well as “multiple letters indicating suicidal intent” on the scene, the report states.
In a statement shared with PEOPLE on Sept. 17, Miller’s manager confirmed that the soap opera star died two days earlier in Austin, Texas. He was 43.
Though no specific cause of death was cited at the time, Miller's manager revealed that he was “struggling with manic depression when he died."
Following the news, Miller's mother Patricia expressed her gratitude for the support she's received since her son's death and shared that Miller "surrendered his life" after "a long hard valiant battle with bipolar depression."
"I want to personally thank the many fans & personal friends for the overwhelming amount of love, prayers & condolences sent to me and my family on the devastating death of my beautiful son BJ — Billy Miller," she said in a statement to Soap Opera Digest. "He fought a long hard valiant battle with bipolar depression for years. He did everything he could to control the disease."
"He loved his family, his friends and his fans but in the end the disease won the fight and he surrendered his life," she continued. "The other causes of death being told are not true. I wish they were but they just aren’t."
"We all loved him so much and are desperately trying to deal with our loss," Patricia concluded. "I will have nothing further to say. Thanks for the love and support."
Following his death, The Young and the Restless paid tribute to Miller, who portrayed the role of Billy Abbott from 2008 to 2014, with a montage featuring his greatest moments on the series.
The longstanding daytime soap closed with a black-and-white photo of the late actor and text that read, “1979-2023.”
