 Troopers said three total rafts were on the river near Copper Center, with Burke, one of four total people on the raft when it became pinned against landslide debris by the river's current and rolled over. Responding officers were alerted just before 6.30 p.m. Sunday, where they helped rescue the group that was in the water. Troopers said the Good Samaritans found Burke's body near the Richardson Highway Bridge and alerted troopers who responded to the area.
