A 45-year-old man was found dead early Thursday in an industrial freezer located at the Channel Fish Processing building in Braintree, prosecutors said.
The man’s co-workers found him shortly after midnight Thursday, said David Traub, a spokesman for Norfolk District Attorney Michael W. Morrissey. Authorities identified the deceased worker as Julio Cesar Costa of Malden.
Costa was pronounced dead at South Shore Hospital.
Traub said there were no apparent signs of foul play. The medical examiner will determine the cause and manner of death.
“The matter remains under investigation, and we have not yet received autopsy information from the office of the chief medical examiner,” Traub said via e-mail.
Roy Zaffiro, chief executive officer of Channel Fish Processing, located at 200 Commerce Drive in Braintree, said in a statement that Costa owned a company that does business with Channel Fish.
“Channel Fish Processing Company of Braintree, Massachusetts can confirm that the owner of Big Star Cleaning of Everett, Massachusetts, an independent company with whom Channel does business, died overnight in a spiral freezer used at the Channel facility in Braintree,” Zaffiro said.
He said his company is “profoundly saddened by this tragedy, and extend our deepest sympathy to the man’s family, friends and co-workers at Big Star Cleaning. Channel Fish Processing Company is cooperating with OSHA, Massachusetts State Police, and local authorities in their investigation. Channel Fish, which has been in business since 1985, is devoted to safety at all times, and is conducting its own investigation.”
