4 people sickened at Lake Stevens post office annex
LAKE STEVENS, Wash. -- Hazardous materials teams were called to the Lake Stevens post office late Tuesday after some complained of feeling sick.

Once crews arrived at the Post Office Annex building at 12101 36th Ave. NE, they determined four people who said they were nauseous should be checked out a local hospital to be safe.

The rest of the 26 employees in the building were all checked and didn't report any problems.

Crews are still working to determine the source of the sickness.
