Boston Firefighters Overcome By Foul Odor

Several city employees have been treated for nausea and rashes after encountering an unknown, foul odor at a vacant Boston warehouse.

Fire department spokesman Steve MacDonald says four firefighters, two EMTs and a city building inspector were overcome after entering the building in South Boston on Tuesday morning. They were decontaminated at the scene by a hazardous materials crew and did not require hospitalization.

The source of the smell was not immediately known, although some described it as something like "dead animals."

MacDonald says officials went into the building after a neighbor reported seeing a truck back up to the building on Monday and leave something behind.
