The body of a man who was trapped in a brick factory in Chesterfield County died on Friday after he was found by a local woman who had been rescued by emergency crews from the roof, authorities said.

John P. Burdick, 42, died at St. James Hospital in Chester, about 80 miles southeast of Philadelphia, where he lived.

His body was sent to the University of Pennsylvania Medical Center in Philadelphia, a hospital spokeswoman said.

Chester County Coroner Jeff Foust said Friday afternoon that he had not yet determined the cause of death.

A woman who answered the phone at the Burdicks home, who did not want to be identified, said Burdicky died Friday afternoon.

A coroner’s official could not immediately be reached for comment.

Chester Police Lt.

Dan Riggs said Bredick was trapped for nearly 12 hours after a fire broke out in the factory, where workers were using a hose to lift the clay.

The fire started about 4:15 a.m. on Tuesday, and firefighting efforts were hampered by the smoke and debris, Riggs wrote in an email.

“We believe that a fire was ignited by the work, possibly in the ovens, and spread quickly, and the roof collapsed,” Riggs told The Associated Press on Friday.

Bredicks death was the first reported death in the brick factory.

Chester Mayor Paul Sarno said Burden had been working there since late October.

A person who answered a telephone number listed for Burdicks mother, who said she was too embarrassed to speak, said the family was not available for comment Friday.

Chester was the scene of one of the deadliest mass shootings in U.S. history in 1996 when the gunman killed 168 people and injured more than 500 more in a church in Charleston, S.C. The incident also prompted a nationwide crackdown on firearms after the shooting, which also took the lives of nine others.

Chester is a city of roughly 4,000 people, about 35 miles southeast.
