One killed, 2 injured in collision at SFO International Terminal

A vehicle at San Francisco International Airport struck three pedestrians on Monday and one has been killed, according to officials. 

San Francisco police are investigating the incident, which happened at around 3:30 p.m. at the arrivals area of the International Terminal. 

Police and SF Fire officials responded to what they call a "multi-motor vehicle collision." Two adult male pedestrians and one adult female pedestrian were taken by ambulance to a local hospital with life threatening injuries. Officials said one of the men succumbed to his injuries about an hour after the incident. 

The driver of a black Ford Expedition accelerated "from the curb prior to the collision", according to preliminary information. A 46-year-old male driver of that vehicle stayed at the scene and is cooperating with the investigation. 

Police said the driver did not appear to be impaired, nor did he show any signs of acting intentionally. 

The police department's Traffic Collision Investigation Unit is in charge of the investigation.
