The state capitol building will reopen Wednesday after an envelope with white powder was found Monday afternoon.
Test results now say the substance has tested negative for hazardous materials, according to final results from the N.C. Division of Public Health.
The Department of Cultural Resources decided to keep the building closed to the public as a precaution until final test results came in. Those result came back late Tuesday. Staff from the Governor's Office, State Capitol Police and Cultural Resources who work in the building were back on the job.
State Capitol Police has opened a criminal investigation into the white powder discovery.
The state capitol building in downtown Raleigh has been evacuated after white powder was found in an envelope.
Perdue spokeswoman Chrissy Pearson told WITN News that is happened a little after 3:00 p.m. She says an administrative staff member opened up the envelope and made the discovery. Pearson says Governor Beverley Perdue was inside the building. Perdue and 40-50 other people were safely evacuated.
Pearson says a haz-mat crew is accessing the situation.
Police and Perdue's staff asked visitors to leave the 170-year-old building, which includes offices for Perdue and the old House and Senate chambers. Two workers who handled the letter also were being checked out.
The governor was in the old House chamber when the envelope was found, signing legislation requiring insurance companies to cover the cost of hearing aids for children.
Pearson said she knew of no threats associated with the envelope. She said the governor stayed outside the building, making sure that all her staff safely made it outside.
