(Longview, WA) -- A woman is in police custody following a four-and-a-half-hour standoff in Longview. Authorities say officers were dispatched to Carl's Towing Service on Vandercook Way around 4:30 yesterday afternoon after a woman entered the business and claimed to be armed. After the building was evacuated, a crisis negotiator worked to persuade the woman to come out after she had barricaded herself inside. The woman surrendered shortly after nine p.m. Police say they don't know why the woman holed herself up in the building.
