NEW YORK (AP) – A New York City man who died of lymphoma and lung disease three months ago has been added to the Sept. 11 death toll.

The city medical examiner’s office says 45-year-old Leon Heyward’s death was caused by breathing in the toxic dust cloud caused by the collapse of the World Trade Center towers.

The medical examiner says Heyward died Oct. 13 of lymphoma, complicated by the lung disease sarcoidosis.

M.E. spokesman Ellen Borakove says Heyward was near the towers when they collapsed. She didn’t know when he had become ill.

In 2007, the office added the name of a woman who died after the 2001 attacks to the death toll because of her exposure to toxic dust. The death toll from the trade center attacks now stands at 2,752.
