One woman is dead after a King County sheriff’s SUV struck her parked car Saturday on a street in Seattle’s Georgetown neighborhood.

The crash happened around 12:30 p.m. along a commercial stretch of southbound Airport Way South near South Nebraska Street.

A King County Sheriff Transit Police SUV struck the silver car from behind, and the woman, who was in her 30s, was in a passenger seat, Seattle Police Department spokesperson Patrick Michaud said. She died at the scene.

Investigators believe the deputy “probably lost control of the vehicle while having a medical emergency,” Michaud said.

Emergency crews extricated the deputy from his vehicle and brought him to Harborview Medical Center. He suffered serious injuries, but was alert and undergoing tests around 2 p.m., a Sheriff Department spokesman said.

The woman’s car struck a utility pole, a commercial building and two other vehicles that were unoccupied. No other injuries were reported.

“I am devastated and saddened by the loss of life,” King County Sheriff Mitzi Johanknecht, said in a statement late Saturday. “I can’t imagine the pain her family is experiencing after their sudden loss,” she said, adding that further updates on the investigation will come from the Seattle Police Department.
