New York Times media columnist David Carr died of complications from metastatic lung cancer, according to autopsy results released Saturday.
The autopsy shows heart disease also contributed to his death, said Julie Bolcer, a spokeswoman for the New York City medical examiner's office.
Carr, 58, collapsed at the newspaper's headquarters and died Thursday.
He wrote the newspaper's Media Equation column and penned a memoir about his fight with drug addiction. He was lauded as "the finest media reporter of his generation" by Times' Executive Editor Dean Baquet.
Carr's 2008 memoir "The Night of the Gun" traces his rise from cocaine addict to single dad raising twin girls to sobered-up media columnist for the Times. The book also detailed his life as a cancer patient as he battled Hodgkin's lymphoma.
