9 killed in horrific North Las Vegas crash

A six-vehicle crash killed nine people and left one person in critical condition in a wreck that police in Nevada said was caused by a driver who was speeding.

The driver of a Dodge Challenger also ran a red light before the collision Saturday afternoon, which involved 15 people, North Las Vegas Police spokesman Alexander Cuevas told reporters at a news conference.

"We have not seen a mass casualty traffic collision like this before," Cuevas said at the briefing around 11 p.m. local time.

The crash was reported at 3 p.m., Cuevas said, after the driver "struck multiple vehicles, causing a chaotic event." Some of the vehicles struck were pushed into a vacant lot on the intersection.

The ages of the people who died ranged from young juveniles to middle-aged adults. Two people were taken to a hospital where one died and the other was in critical condition, Cuevas said.

It was not yet known whether the driver of the Dodge was impaired.
