A man was arrested in connection with the crash that killed one person, and sent another flying off the freeway and into Temecula City Hall parking. Tony Shin reports for the NBC4 News at 6 p.m. Tuesday, June 4, 2019.

The crash occurred on Interstate 15 a little before 7:30 a.m. near Rancho California Road, the Riverside County Fire Department and the California Highway Patrol said. At least five vehicles in all were involved, and one car went flying off the road and into the parking structure at Temecula City Hall.

A gray Chevy Silverado speeding on the freeway was seen in frightening surveillance video ramming into the back of a sedan, apparently not applying the brakes at all. Video from another driver's rear-view camera shows the pickup swerve from the shoulder of the road, cutting across lanes at an alarming speed.

The victim's car was flattened by the impact, and another White Chevy Tahoe sustained major damage.

Two people managed to survive the crash without serious injuries while others were hurt, authorities said.

All lanes of the freeway were closed initially, but were later reopened.
