Maryland officials say two employees opening mail at separate state office buildings had their fingers burned when they opened packages that emitted smoke and fire.
Mailrooms at other state offices across Maryland are being quarantined until it can be determined if any other packages have been sent.
Shipley says the packages did not explode but there was a flash of fire, smoke and a smell with each.
One package was opened at a state office building just blocks from the State House in downtown Annapolis. Another was opened 15 minutes later at the Maryland Department of Transportation headquarters.
