Two vehicles crashed on a snowy Interstate 80 in Wyoming on Monday, setting off a chain reaction of collisions that killed one person and left dozens of other vehicles in a fiery pileup, NBC News reported. A canadian man, Alex Dragaytsev, was arrested and charged with aggravated vehicular homicide, the Wyoming Highway Patrol said. A 22,000-gallon tanker truck carrying hazardous material caught fire in the crash, but the WHP said officers didn't think any dangerous materials were released in the crash.
