(Portland, OR) -- Authorities say that fires set in ballot boxes in Oregon and Washington State are linked. Fires at two ballot boxes in the Portland area yesterday have been linked through the discovery of incendiary devices to a fire at a Vancouver, Washington ballot box earlier this month. Portland Police have identified a suspect vehicle caught on video yesterday, saying it appears to be a black or dark-colored 2001-to-2004 Volvo S-60 that is missing a front plate and has an unknown rear plate. Anyone with information on that vehicle or the fires is asked to call police.
