The Walla Walla County Public Safety Building will be open for business on Monday following Friday’s incident involving an unknown powder which forced an evacuation.

Undersheriff Edward Freyer says a criminal investigation has begun after a woman made a mysterious delivery to the Walla Walla County Sheriff’s Office Friday afternoon.

The woman, suspected of having some mental health issues, believed her prescription medication was contaminated and delivered a plain envelope containing capsules to the Sheriff’s Office receptionist for Sheriff John Turner to examine.

Turner was not in the office at the time the envelope was delivered, however, upon arrival Turner opened the envelope and some of the capsules broke open, spilling a white powdery substance.

Unsure what the powder was, the building was evacuated and Turner and additional staff members were taken to a local hospital for examination.  It was later determined the substance was harmless and Turner and his staff were unharmed.

A hazardous materials team was also set up to help with decontamination.

Investigators were able to locate the woman who admitted she delivered the envelope and that it contained medication.
