Hurricane Maria hit Puerto Rico in September. 

In the weeks that followed, residents suffered without power and other necessities.

Three months after the hurricane, the island's power generation abilities are only 64 percent of what they were before the storm, ABC News reports. Nine of Puerto Rico's 78 municipalities have no power whatsoever.

The Army Corps of Engineers blames the slow progress on a lack of supplies. A spokesperson for Puerto Rico's power union said that supplies are available, but the money to buy them is not. He told ABC that one town got its power back only after residents pooled their own money to buy the supplies needed to repair their electric grid.

Beyond power woes, a new report from the Center for Investigative Journalism has found that the storm's death toll on the island has been grossly underreported. 

As TIME reports, the death toll was previously reported to be 64. The actual death toll exceeds 1,000 people.

The 64 people who were officially counted in the post-hurricane death toll had death causes including flood drowning, mudslide entrapment, deaths caused by heart attack and other medical conditions, including injuries suffered from falling debris.

Now that the new number has been announced, people are angry and want answers as to how such a huge mistake could have been made.

Puerto Rico Governor Ricardo Rosselló assured the concerned this week that the mishap wasn't intentional. 

“We always expected that the number of hurricane-related deaths would increase as we received more factual information — not hearsay — and this review will ensure we are correctly counting everybody,” Rosselló told the Washington Post. 

Rosselló has demanded an official recount, including investigating whether determined "natural" death causes were actually caused by the storm. 

Rosselló wants the official count since the government “cannot base any official fatality related to the hurricane count on statistical analysis.”

“Every life is more than a number, and every death must have a name and vital information attached to it, as well as an accurate accounting of the facts related to their passing,” the governor said.
