“There were at least several dozen additional victims, possibly hundreds,” Pascual reported, citing sources from nine hospitals, police, morgue directors and others in Puerto Rico.

Another official, health secretary Rafael Rodríguez-Mercado confirmed that at least three hospitals had notified him of additional victims. According to Pascual, hospital staff told the health secretary some people had buried their family members in mass graves “given the impossibility of communication and transportation due to María’s impact.”

"Everything in the government has collapsed," Pascual told Vox. "Some of the people who work in the government lost their homes themselves and aren't at work. So they can't do death certificates. The dead can't be documented because of all the logistics and legal aspects of declaring someone dead."

Pesquera also noted that without the proper communication and lack of death certificates, it hasn’t been possible to analyze which deaths were natural or due to the disaster.

When he gathered hospital executives after CPI released the report last week, they told him there was no accumulation of corpses in their morgues.

But the Doctor’s Hospital and the Veterans Hospital told CPI media that the military had shown up to remove bodies at their institutions. At the Veterans Hospital, there were 26 corpses.

“I’m not saying it has not happened, I’m saying we can only certify what we know. When that information arrives, we will validate it. I’m not going to hide any numbers. I’m not going to hide any data,” he said, and added that the process could take months.

It’s the duty of the mayors, those closest to the citizens, to collect the information, Pesquera said. He also urged people to report missing persons to their nearest police station or City Hall.

On Monday, Pascual reported, there were 30 people missing at the Puerto Rico Police Department.
