Authorities in Utah say a man drove his pickup truck into a crowd gathered at a Starbucks on Friday, killing one customer and injuring several others, including the driver.

According to Fox News, an initial investigation indicates the incident was not intentional.

Police report the collision occurred at a shopping center in Millcreek, a short distance from Salt Lake City.

The woman killed was identified by Unified Police of Greater Salt Lake Sgt. Melody Gray as 48-year-old Joslyn Nicole Spillsbury of Salt Lake City.

Gray did not identify the driver by name but said he is a 34-year-old man from Oakley. He was also among three individuals who sustained critical injuries during the crash.

Reports indicate his truck careened off the road and into a pillar supporting the coffee shop patio about 100 feet away. Police believe the driver was impaired by a medical issue, potentially a seizure.

Both the Starbucks and an attached Sports Clips location were closed in response to the crash after officials determined the building to be structurally unsafe. Temporary support was set up so police could conduct their investigation, according to Deseret News.

The vehicle crashed into an area where three individuals were seated. In addition to Spillsbury’s fatal injuries, the collision critically injured the two people sitting with her.

Two small children were reportedly inside the truck at the time. Both were assessed for minor injuries.

Salt Lake County Sheriff Rosie Rivera said that she saw two individuals at the scene comforting the young passengers. Their mother reportedly arrived a short time later and transported them to the hospital.

It was still unclear as of the latest reports available whether authorities are planning to pursue criminal charges against the driver.
