A suspected impaired driver determined to escape from police led troopers on a wild chase in Tacoma and across the Narrows Bridge before finally being captured in Gig Harbor.
The ordeal began around 5:30 a.m. when Tacoma Police spotted a car believed to have been involved in a hit-and-run, but the driver wouldn't pull over and sped off, according to Trooper Johnna Batiste.
