The body of a man was found on the Brockton campus of the VA Boston Healthcare System on Sunday morning, officials said. The man, whose name was not released pending notification of family, was found at 9:10 a.m. inside a structure that is at the facility to shelter people from inclement weather, according to Pallas Wahl, a spokeswoman for the Department of Veterans Affairs. The man’s death is not believed to be suspicious, Wahl said, but state and local agencies are investigating. “The VA’s office is really upset that this has happened,” said Wahl. No further information was available Sunday afternoon.
