LYNNWOOD — A suspicious substance found in a letter at a Lynnwood business Wednesday turned out to be nontoxic, Lynnwood police reported.
The letter was opened around 10 a.m. at a debt-collection business in the 20700 block of 44th Avenue W. It contained documents and what police described as a suspicious substance.
Police learned that an employee had received a threat the day before, Cmdr. Jim Nelson said. However, it was not known Wednesday whether there was any connection between the threat and Wednesday’s letter.
“We are not going to get into details of the substance until the investigation is complete,” Nelson said. Firefighters wore hazardous material suits when they entered the business before determining it was nontoxic.
“The Lynnwood Police Department is actively investigating this incident to identify potential suspects and to identify whether a crime has been committed,” Nelson said.
The case has been assigned to a detective.
