Washington State Patrol Detectives Mike Gradwohl, left, and Bill Bryan use a rangefinder to record measurements Monday as trooper Oscar Garcia holds a reflector above them on the Interstate 182 bridge over the Yakima River as they investigate a fatal accident. Joevani Olivera, 16, of Kennewick, died when the Honda Accord he was riding in Sunday plunged off the bridge. Scrape marks and investigative paint markings are visible on the concrete barrier behind Garcia.
A dangerous weekend on Mid-Columbia roads left families and friends mourning the loss of three young people, troopers investigating multiple crash scenes and two drivers behind bars.
