According to a coroner's report for the singing legend's son obtained by Radar, Craig Turner, 59, spoke about his financial problems before taking his own life in July.
The shocking report explained that Craig's sister-in-law told police that he "had recent financial problems and was upset the family management had reduced his family income."
The sister-in-law – who discovered Craig's body on June 29 after entering his home to check on him – further claimed Craig was a former alcoholic who had "begun to drink again recently."
According to the report, others close to Craig claimed he displayed bizarre behavior in the days leading up to his death.
A male informant told authorities that he spoke with Craig six days before his death and observed "he was not his normal self," the report claimed.
Police also observed three handwritten suicide notes on Craig's kitchen counter on the day of his passing, the report revealed.
The coroner's report confirmed that Tina's oldest son shot himself using a revolver inside of his two-bedroom Studio City, Calif. home on July 3.
Craig's neighbor previously told Radar that Craig never talked about his famous mother.
The coroner's report claimed that Tina, 78, was notified of her son's sudden death by authorities via telephone.
The Los Angeles Coroner's Office confirmed his cause of death was a gunshot wound of the head, and the manner was suicide. Foul play was not suspected, the document said.
