A driver is under investigation for DUI after a fatal crash that also led to the power being lost to thousands of Enumclaw residents.

According to Puget Sound Energy and the Enumclaw Police Department, the outage occurred at 12:26 a.m. when a 2013 Ford F-150, traveling west out of town, crashed near the intersection of Roosevelt Avenue and state Route 410.

“Witnesses said the truck was traveling… through town at over 100 miles an hour,” said Commander Tim Floyd of the EPD. “They failed to negotiate the curve and went off the road, across the ditch, and hit the power pole.”

According to Floyd, there were four passengers — one was ejected from the car and was dead on arrival.

Two others were transported to Harborview Medical Center, one by ground and the other by air. Their status is unknown.

The driver was transported to Valley Regional Medical Center for head trauma, and is under investigation for DUI, Floyd continued.

The names of the driver and passengers have not been released.

According to PSE, the power outage that resulted from the crash impacted more than 7,000 Enumclaw residents; power for the majority of folks was restored by 1:50 a.m., and the rest by 4 a.m., a spokesman said.

This is a developing story and will be updated as more information is released.
