Kevin Marnell, a Portland electrical engineer, took cellphone footage of two teenagers being detained by Oregon state troopers near the Cascade Salmon Fish Hatchery. A witness at the scene identified them as the people who tossed the fireworks that started the blaze.
Law-enforcement officials have declined to discuss details of the suspects who they believe started the fire. But Oregon State Police told KATU-TV on Sunday that one suspect is a teenage boy.
