Cornstarch in mail leads to emergency response at office
The suspicious powder responsible for a lockdown at a North Issaquah office building Jan. 13 turned out to be cornstarch.
Issaquah police and emergency crews mobilized to the building in the 1600 block of Northwest Sammamish Road at about 2 p.m. after receiving reports of a package containing a powdery substance. Responders said a handful of workers reported headaches and sore throats.
The incident occurred at the Costco-owned and operated Lake Place Office Center, about a mile from Costco and Costco headquarters.
Eastside Fire & Rescue sent a hazardous materials team to retrieve and remove the package. Officials also locked down the building and cordoned off the area for several hours.
The investigation expanded to include the police department, the FBI and the U.S. Postal Inspection Service, the agency responsible for mail-related crimes.
