Police said Nancy Sullivan, 57, was driving on the Taconic state parkway on Thursday night when the vehicle left the road and struck a rock embankment in LaGrange, 110km north of New York city.(…)She was known as a staunch advocate for Papua New Guinea’s residents whose way of life is threatened by logging and mining. In an interview with Radio Australia, John Chitoa, an official with a Madang non-government organisation, referred to Sullivan as “a great warrior” for the people.
