SAN JUAN, P.R. — Puerto Rico’s official death toll from Hurricane Maria more than doubled from 16 to 34 two weeks after the storm as a result of a full accounting intended to add up the piecemeal reports from around the island, Gov. Ricardo Rosselló said Wednesday.

Governor Rosselló said at a news briefing Wednesday that he had commissioned the accounting to add up the reports slow to arrive from devastated hospitals and local medical agencies. The new tally may still not be complete, but it offers the clearest picture yet of the death toll and how people died during and after Maria, he said.

Nineteen people were killed directly by the storm — by drowning, being buried in mudslides, struck by falling objects or otherwise, Governor Rosselló said. He said the others had died indirectly — from a heart attack or suicide, or because they languished without oxygen or necessary medical care as hospitals floundered without power and patients were cut off from care.

“We were not able to aggregate this complete set of data before,” Governor Rosselló said. “We were getting little bits of certified data, but after yesterday’s effort, we have a more complete picture of what has occurred in terms of direct deaths due to the storm and indirect as well.”
