A semi-truck has collided with a Greyhound bus in New Mexico, killing at least 7 people and injuring dozens more. New Mexico State Police believe the truck's tire blew on Interstate 40, causing the massive vehicle to glide across the median before smashing into the bus. Most of its passengers, who were headed to Los Angeles from St. Louis, were hospitalized, authorities said. InsideEdition.com's Leigh Scheps (http://twitter.com/LeighTVReporter) has more.
