The body of Maeve Kennedy McKean, granddaughter of assassinated presidential candidate Robert F Kennedy, has been found in Maryland.
The 40-year-old and her eight-year-old son were last seen on Thursday evening riding in a canoe off Chesapeake Bay.
After an extensive search operation, police announced Monday that her body had been found in water about 2.5 miles (4km) south of where they had set off.
Officials will continue looking for her missing son, Gideon, on Tuesday.
Mrs McKean was the daughter of Kathleen Kennedy Townsend, the former Maryland lieutenant governor. She worked as a public health and human rights lawyer and was executive director of Georgetown University’s Global Health Initiative.
She had been staying with her family at her mother’s house in Shady Side, Maryland, when she went missing.

Her husband, David McKean, said in a Facebook post that they had been “self-quarantining” there away from their usual residence in Washington DC in order to give their children more space.
