One worker has died after firefighters battled a massive, five-alarm blaze that broke out Thursday morning at a construction site in Charlotte, North Carolina.
The deceased worker was identified as Demonte Smith. His father confirmed his death.
A second worker remains missing. The fire captain told CBS News that on Thursday night, structural engineers deemed it unsafe for heavy machinery to operate overnight, so search and rescue efforts were paused until morning. Efforts resumed in the morning as machinery was used to search under debris.
There are concerns that the entire structure is unstable and could collapse, the captain said.
More than 90 firefighters were called to the scene and had not yet extinguished the fast-moving flames, said Charlotte Fire Chief Reginald Johnson at a news conference held hours after flames initially erupted around 9 a.m. ET.
