Investigation of Boston warehouse blaze begins; officials calling it biggest fire in decades

An investigation into one of the biggest fires in Boston in decades is getting under way.

About 170 firefighters from across the city battled the blaze that razed a vacant warehouse in the city's Roxbury neighborhood over the weekend. The fire was reported on Saturday night and was not completely out until Sunday afternoon. No one was hurt.

The blaze caused an estimated $750,000 in damage.

Warehouse owner Candeloro Maggio Jr. says he used to run a frozen food storage business at the site but shut the operation down about three years ago because chunks of concrete from a six-story building next door kept falling on his building.

He says he told the city, but nothing was done.

A spokeswoman for the mayor's office said Maggio's claims will be investigated.
