Autopsy results show New York Times media columnist David Carr died of complications from metastatic lung cancer.

Julie Bolcer (BOHL-suhr), a spokeswoman for the New York City medical examiner's office, says the autopsy shows heart disease was a contributing cause of death.

Carr collapsed at the newspaper's headquarters and died on Thursday. He was 58.

He wrote the Media Equation column for The New York Times and penned a memoir about his fight with drug addiction. He was lauded as "the finest media reporter of his generation" by the 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.
