Mary Kennedy, the estranged wife of Robert F. Kennedy, Jr., had three types of antidepressants in her bloodstream when she died, according to an autopsy report.

Kennedy, 52, was found dead at her home in New York in May (12) in an apparent suicide after a long battle with alcohol. She died of asphyxiation due to hanging.

Documents from her autopsy, obtained by the New York Post, reveal tests show she had at least three antidepressants in her blood, but there was no sign she had been drinking booze prior to her death.

Officials found traces of trazodone, desmethylvenlafaxine and venlafaxine in her body, according to the publication.
