Evidence from the incendiary devices found at the ballot boxes Monday show the fires are connected, as well as a third incident reported in Vancouver, Washington, on October 8, said Mike Benner, a spokesperson for Portland Police Bureau. While many of the ballots in Portland were unaffected, hundreds of ballots were destroyed in a Vancouver ballot box, election officials said.

Portland police also identified a “suspect vehicle” seen leaving the scene of the fire in Portland, which is believed to be tied to the two incidents in Vancouver as well, they said in a news release Monday. The car appears to be “a black or dark-colored 2001-2004 Volvo S-60” that’s missing a front plate and has an unknown rear plate, they said.

Portland police released photos of the suspected vehicle connected to the ballot box fire in Southeast Portland early Monday morning.
