Police say they have identified a "suspect vehicle” connected to incendiary devices that set fires in ballot drop boxes in Oregon and Washington state early Monday.
The ballot drop boxes in Washington and Oregon both have fire suppression systems that are designed to activate when the temperature inside reaches a certain point, coating ballots inside with a fire-suppressing powder.
For unknown reasons, the system failed to prevent the destruction of hundreds of ballots in Vancouver, just across the Columbia River from Portland.
