( CNN ) -- The body of Mary Kennedy , the estranged wife of Robert F. Kennedy Jr. , was moved to `` a sunny hillside '' in a separate section of the Cape Cod , Massachusetts , cemetery where she was originally interred two months ago , her family said . Kennedy , who had been battling depression , was found dead May 16 in Bedford , New York , a small town north of New York City where she lived . The medical examiner 's office determined Kennedy died as a result of asphyxiation due to hanging . She was 52 . The decision to move her grave in St. Francis Xavier Cemetery was made because the original plot was closely surrounded by other graves with no room for expansion , Kennedy family spokesman Ken Sunshine said . Toxicology results : No alcohol in Mary Kennedy 's system . `` The grave is now on a sunny hillside , shaded by an oak tree in an area with room for her children and other family , '' Sunshine said . Kerry Kennedy , Mary 's best friend and sister-in-law , and two of Mary 's children selected the new gravesite last week , he said . Kennedy family members have since purchased some 50 plots surrounding the grave , including plots reserved for all six of Mary and Robert Kennedy Jr. 's children , he said .
