She was killed, in disputed circumstances, at the age of 27, by American forces while travelling on a trail in the Ba Tơ jungle in the Quảng Ngãi Province of south-central Vietnam. Her wartime diaries, which chronicle the last two years of her life, attracted international attention following their publication in 2005.
