Smoking Packages in Maryland Work of 'Lone Wolf'

The sender of two packages that released smoke when they were opened in Maryland yesterday was a “lone wolf,” not affiliated with any group, said a congressman briefed on the matter. Maryland’s governor, to whom one package was addressed, said it contained a note deriding highway signs that call on drivers to "report suspicious activity." "Somebody doesn't like seeing that sign," he said.

“I believe this is what we call in intelligence a lone wolf situation, involving an individual who for whatever reason was upset with state government,” said Maryland Rep. Dutch Ruppersberger. Postal employees returned to work today, but officials remain on alert as the FBI investigates, the AP reports.
