She was at the compound, where her grandmother, Ethel Kennedy, lives. Emergency-responders were reportedly called on Thursday afternoon, The New York Times said.
Meanwhile, local authorities issued a statement confirming a death at the property but did not disclose the identity of the deceased.

The Kennedy compound on Cape Cod was the summer residence of the famous 20th century political heavyweight Kennedy family. The venue was also a base of operations for the presidential campaign of John F. Kennedy in 1960 and later served as a summer White House.
President Kennedy and his brother Senator Robert F. Kennedy were both slain by assassins.
