A hazmat team responded to an office building in Lynnwood after a worker opened a letter at 10 a.m. on Wednesday and found a suspicious substance inside.
Lynnwood Police went to the scene and found out an employee received the threat on Tuesday. Lynnwood Fire was called. Eventually a Snohomish County hazmat team arrived and determined the substance was non-toxic.
Lynnwood Police is investigating the incident.
“We are not going to get into details of the substance until the investigation is complete,” Lynnwood Police Commander Jim Nelson said. “I also can’t describe the substance as we may need to withhold certain information that only the party that sent it would know in order to determine the veracity of any statements that the suspect, if contacted, would provide.”
Investigators have not yet determined if Tuesday’s threat is connected to Wednesday’s incident.
Nelson said the business where the substance was found, located at 20700 44th Ave. W. in Lynnwood, is a debt collection business. The threat letter appears to be related to the business, not a relationship between a particular person and the suspect(s).
The incident has been assigned to a detective.
