 Fire crews believe a major fire at an old Burien school building was intentionally set. Here's Como 4's Lee Stoll. This is at Southern Heights Elementary School. It closed a few years ago because of low enrollment, but about 100 students still use the building for Highline Virtual Academy and Innovation Heights Academy. They're out for the summer. I did speak to the battalion chief who made the call to upgrade this to a two-alarm. Putting water onto the fire.
