Authorities said the crash happened eight minutes from the domestic violence call he was heading towards.
"One of the people involved in the domestic violence had armed themselves with a shotgun, so our deputy called for backup," Detective Ed Troyer, a spokesman for the Pierce County Sheriff's Department, told KIRO-TV.
Troyer said Dyson was speeding around 3 a.m. Saturday when he lost control of his patrol car.
“(He) had his lights and siren on,” he said. “(There were) no other cars on the road.”
Authorities believe Dyson hit a patch of water, hydroplaned, barrel-rolled and landed before his patrol car burst into flames.
“Unfortunately, he was trapped inside the car,” Troyer said. “By the time anybody got here, it was fully engulfed. The car burned, and he lost his life.”
Dyson was married with one child and a second child on the way
