New details are emerging about explosive devices placed in ballot boxes early Monday in Portland and Vancouver, Washington.

At a news conference Wednesday, Portland Police released their first description of a suspect. Agency spokesperson Mike Benner said the suspect is a white male, between 30 and 40 years old.

“We believe this suspect has a wealth of experience in metal fabrication,” Benner said. “It’s very possible the suspect continues targeted attacks across the area.”

Benner said law enforcement believes the same person is connected to both incidents Monday, as well as a third incident that took place on Oct. 8 in Vancouver where the incendiary device did not go off.

This is a developing story and will be updated.
