Christopher Neal, director of public safety and security for the Port of Portland, was watching planes land with his family when he saw the suspect place a grey mask over his face and jump the fence.

"Immediately I thought, 'It's a little hot to have this hoodie on,' and just as he walks by our car and looks at us and just got past that's when he pulled the gray mask over his face," he said.

The FBI said they are aware of the situation at the Hillsboro Airport and are working in coordination with local authorities.
