(AP) VALHALLA, N.Y. - An autopsy report shows the estranged wife of Robert F. Kennedy Jr. had three antidepressants but no alcohol in her system when she committed suicide in New York.

Westchester County released the medical examiner's report on Mary Richardson Kennedy on Friday. The 52-year-old architectural designer and environmentalist hanged herself in May at her family's estate in Bedford, just north of New York City. Family members say she fought a lifelong struggle against depression.

Kennedy married Robert F. Kennedy Jr. in 1994. The couple had four children.

He filed for divorce in 2010, asking in court papers she be required to remain sober in front of their children and not threaten suicide in their presence. Her family accused him of using the filings as a "brutal psychological weapon."
