I cannot imagine what this guy saw.
"Daniel Konzelman was one of thousands of commuters barreling along a highway outside Seattle on Monday morning when the emergency response training he learned as an Eagle Scout kicked in."

Report said he was on scene for nearly two hours. I hope post trauma counseling is available to responders.
CBS This Morning had a video interview, Eagle Scout Hero.
