LARGO — Authorities were called to the Pinellas County Courthouse on Monday afternoon after the discovery of a suspicious package that contained a dirty white powder and a letter containing death threats.
Initial tests showed nothing toxic in the powder, but it was taken to the University of South Florida for additional testing, said Teresa Del Rio, manager of criminal court records for the Pinellas County Clerk's Office. The powder resembled concrete dust, she said.
The package also contained a letter that made death threats, but Del Rio did not have specifics because the entire package was given to emergency workers, she said. The letter had a return address from a Florida prison, she added.
Hazardous matertials crews from Pinellas Park and Largo fire departments responded to the criminal complex at 14250 49th Street N shortly after 1 p.m. after someone on the second floor got the envelope, sheriff's spokeswoman Cecilia Barreda said.
The courts are closed today in observance of Rosh Hashanah, but the clerk's office is open. Few people were inside the building, Barreda said.
