New Hampshire inmate causes anthrax hoax

Investigators in New Hampshire have reported that an inmate serving a life sentence sent an envelope to the superior court in Nashua that contained a suspicious power that led to a building evacuation.

After the envelope was found on Wednesday, parts of the Hillsborough County Superior Court building were evacuated for fears of a hazardous material, the Boston Herald reports. The message accompanying the letter claimed that the powder was anthrax, but tests by hazard teams showed there was nothing toxic in the letter.

The inmate’s name has yet to be released due to the ongoing nature of the investigation.

The powder was received at approximately 8:30 a.m. at the Clerk’s Office of the building in the Southern District in Nashua, according to a press release by the Nashua Police Department. Nashua police officers responded to the scene, as did the Hazardous Materials Unit of the city’s firefighters.

After field testing proved negative, the powder was sent to the New Hampshire Public Health Laboratory in Concord for a more thorough analysis. The investigation continued with detectives assigned to the Nashua Police Department’s Criminal Investigation Division, the Federal Bureau of Investigation's Bedford Office, the Hillsborough County Sheriff’s Department and investigations with the New Hampshire Department of Corrections.
