Charges have been dropped against a woman who was accused of phoning in a bomb threat that closed down county offices in April.  

According to court records, Teresa Pickering, 50, was accused of making repeated calls to emergency dispatchers saying she "was gonna blow it all up."  The woman who called 9-1-1 dispatchers said "it" was at the Galena City Hall and the courthouse. No bomb was ever found.

Investigators tracked the calls to a Tracfone that had been purchased at an area Walmart store about 20 minutes before the first bomb threat was made.  "It could have been a case of mistaken identity," said Stone County Prosecutor Matt Selby.

"We just didn't have sufficient evidence at this time to proceed," said Selby.  "There was sufficient evidence for a probable cause arrest, but as the investigation continued I didn't think we had enough to prove guilt beyond a reasonable doubt and I thought it was best to dismiss the charges at this time."

Selby says the investigation into the incident is ongoing.  

County officials made the decision to close all county offices on the day the threat was made to ensure the safety of employees and the public.
