Officials in the Caribbean country say Kershaw's body was found at her home in the northern town of Sosua, where she moved with her husband, William Norton, in 2014. Norton was being questioned about her death, according to Osvaldo Bonilla, a prosecutor for the province of Puerto Plata.
Bonilla said yesterday that authorities had not ruled out suicide or homicide in Kershaw's death.
Norton is an editor and writer who has worked for a number of US publications. Kershaw, 49, worked as a reporter for The New York Times from 2000-2011. She previously worked for Newsday, among other publications, and was a freelance writer at the time of her death.
