Baltimore Fire Department Chief Roman Clark said that one of the victims was an adult male who was found trapped underneath heavy debris at the Amazon warehouse.
Fire officials responded to a call about a potential collapse of the Amazon Fulfillment Center building at around 10:30 p.m. on Friday night. That person was taken to a hospital and declared dead, per CBS Baltimore; a second body was found early Saturday, officials say.
According to the reports, a weather-related building collapsed at Amazon's distribution warehouse in Baltimore's southeast in Maryland on Friday.
The National Weather Service will have to determine if weather was ultimately a cause in the collapse, CBS Baltimore reports.
Roofs were reported to have been blown off apartment buildings in Dundalk, Maryland, while sections of ceilings were said to have fallen in at the Twin Arch Shopping Center's TJ Maxx and HomeGoods store.
Amazon's senior vice-president of operations, Dave Clark, said in a tweet on Saturday there were two fatalities at the site, on the south-east side of the city.
Amazon closed the entire building following the wall collapse.
"We are incredibly thankful for the quick response from emergency services", she added. "Our thoughts and prayers go out to those impacted by yesterday's tragic event".
