30 median fires in Kennewick

KENNEWICK, Wash. -- Nearly 30 fires have started in Highway-240 median this summer. They've all been near Edison Street. But firefighters aren't convinced a serial arsonist is on the loose.

The fires may have started accidentally, by tossed cigarettes. But it's strange they've consistently been in a similar spot. The fires have all been put out quickly. But two serious car accidents have been caused as a result of rubbernecking.
