New Hampshire police set to release identity of anthrax hoaxer

Police in Nashua, New Hampshire, plan to announce the identity of the convicted murderer who closed part of the Hillsborough County Superior Court via an anthrax threat during the March insanity trial of Christopher Gribble.

The envelope sent to the building was labeled “anthrax spores,” the Nashua Telegraph reports. While police have identified the sender, they have not yet released the inmate’s name since no charges have been filed.

Lt. Jeff Bukunt of the Nashua police said that the police plan to release the name at the conclusion of the investigation.

After the letter arrived at the courthouse on March 23, the clerk’s office was evacuated. Firefighters arrived in protective suits and, after running several tests, determined that the substance was harmless, the Nashua Telegraph reports. The substance is currently being evaluated by the Public Health Laboratories to determine what it is.

All mail going into the state’s prisons is inspected, but outgoing mail is “a little more difficult,” Jeff Lyons, spokesman for the state prison system, said, according to the Nashua Telegraph. “It really depends on the circumstances of how it was mailed.”

Prison staff are not allowed to open letters marked “confidential” or legal mail. The inmate is likely to face disciplinary proceedings with the prison whether or not additional charges are filed.

No one was harmed as a result of the powder and business continued as usual in the rest of the courthouse when the clerk’s office was closed.
