One person was killed and another was injured Tuesday in a collision between a semitruck and a Mercedes SUV near the intersection of Airport Way South and South Spokane Street in Seattle’s Sodo neighborhood, according to police and fire officials.

Seattle police say the SUV was fleeing after an officer tried to pull the driver over.

At about 7 a.m., a patrol officer tried to pull over the SUV for a traffic infraction in the 1000 block of Fourth Avenue South but the SUV sped off, running a red light and rear-ending a parked vehicle, according to Seattle police. Rather than chase the SUV, the officer broadcast the vehicle’s description.

The crash occurred a few minutes later as the SUV — which police say was speeding — was being driven south on Airport Way South. It collided head-on with the semi, which was going north on South Hinds Street, according to police.

One of two people in the SUV was declared dead at the scene; the other was taken to Harborview Medical Center in critical condition with life-threatening injuries, according to Seattle Fire Department spokeswoman Kristin Tinsley and a Seattle police blotter post. The driver of the semi was not hurt, Tinsley said.

Seattle police did not disclose what the initial traffic infraction was, or any other information about the people in the SUV.
