Key points. Two packages ignited shortly after being opened in two separate government buildings in Maryland. Investigators are examining two additional suspicious packages in a courthouse and a state office building in Baltimore.

The first device ignited in the mailroom of the Jeffrey Building, located in the state capital of Annapolis. A second device ignited at the state’s Department of Transportation headquarters, located in Hanover, Maryland. Two people suffered minor burn-related injuries. No claim of responsibility has been made.

Details of Incident. On Thursday, January 6, 2011, two incendiary devices concealed in packages ignited in two government office buildings in Maryland. At approximately 12:30 pm, a package addressed to Governor O’Malley ignited when it was opened in the mailroom of the Jeffrey Building located at 16 Francis Street in Annapolis. The mailroom attendant who opened the package suffered minor burns on his hands. The Jeffrey Building houses several different offices of the Maryland state government, including Homeland Security, Veterans Affairs, and the Secretary of State.

At approximately 12:45 pm, a second package of similar size and color ignited when it was opened in the mailroom of the Maryland Department of Transportation, located in Hanover, MD. The state employee who opened the package suffered minor burns, and several others were transported to medical facilities as a precautionary measure.
Both ignitions included a brief flash of fire, smoke, and an odor. Officials evacuated both buildings following the incidents. No claim of responsibility has been made regarding these incendiary devices.

Conclusions. Several factors suggest that the two devices that ignited may be linked: reports indicate that the packages were of a similar shape and color; both packages targeted government officials and buildings; and the devices ignited within approximately 15 minutes of each other. Moreover, the two devices that ignited appear to have been either poorly constructed or not intended to cause severe injury. The deliberate targeting of Maryland’s governor and state office buildings suggests that these attacks may have been motivated by anti-government sentiment.

Implications for New York City.

• New York City remains a major target for terrorist groups and individual domestic terrorists. 
• Explosive and incendiary devices concealed as packages have been used in the past by international and domestic terrorists and anarchists in attacks against civilians and government personnel.
• Mailroom personnel, especially those working in government offices (JCRC comment: and Jewish organizations), should remain vigilant and keep an eye out for unusual activity and suspicious packages.

JCRC comments: Later reports indicate that the standard yellow padded envelopes had both excess postage and a fictional return address. Both are  standard indicators of suspicious mail. See JCRC’s guidance on screening suspicious packages and mail here.
