Police say the man behind ballot box fires has metalworking experience and might plan more attacks

Investigators say the man suspected of setting fires in ballot drop boxes in Oregon and Washington state is an experienced metalworker and may be planning additional attacks. Portland Police Bureau spokesman Mike Benner said Wednesday that authorities believe the man who set the incendiary devices at ballot boxes in Portland and nearby Vancouver, Washington, had a “wealth of experience” in metal fabrication and welding. The suspect is described as a white man, age 30 to 40, who is balding or has very short hair. Police previously said surveillance video showed the man driving a black or dark-colored 2001 to 2004 Volvo S-60. The vehicle didn't have a front license plate but did have a rear plate with unknown letters or numbers.
