Right now, troopers want your help finding a driver connected to a deadly seven-car crash on I-5 this week. FOX 13's Sam Campbell live in South King County with the latest here. Sam, what's going on? Well, Taylor, you know, we brought this to you first on Friday morning as the backup continued, but we are now learning new details from the Washington State Patrol about the crash that happened on I-5, the northbound side just there. And you can see it's moving freely now. That was not the case Thursday night into Friday morning. And we are now learning that that street racing led up to that crash. And so that is where multiple cars collided Thursday night around 930, leaving one person in hand or one person dead, another person in handcuffs. The crash left nearly all of I-5 North closed the entire night and into Friday morning. The investigation being intensive and facts were sparse then. But we are now hearing from the Washington State Patrol what drivers saw before the collisions. And so callers told authorities they saw a black Lexus. And a white Infiniti sedan racing down the freeway, speeding in the dark with no lights on. Troopers say the black Lexus crashed into multiple other cars, killing one person and leaving. Numerous others with serious injuries that Lexus driver was arrested on suspicion of vehicular homicide and vehicular assault, but troopers say the driver of the Infinity did not stop, and now they're asking the public for help in tracking down that Infinity driver. So if you know anything, reach out to the Washington State Patrol. But for now, live in South King County, Sam Campbell, Fox 13 News.
