Las Vegas, NV : Man dies after car crashes with semi tractor-trailer on Interstate 15 north of Las Vegas on Saturday January 9 2016.

A man died over the weekend when his Cadillac crashed into the back of a semi tractor-trailer on Interstate 15 north of the U.S. Highway 93 off-ramp.
The Clark County coroner identified the driver of the Cadillac as 43-year-old Carson Keel Winget of St. George, Utah.
