The police investigation determined a 2007 Chevrolet Silverado pickup truck driven by Parrish was southbound on 108th at a high rate of speed as it approached the Charles Street intersection. Just before Charles Street, police said, the pickup crossed into the northbound lane of 108th Street, left the roadway on the east side and struck a wooden power pole. After hitting the power pole, the pickup rolled several times and Parrish was ejected from the truck.

Reports to Douglas County emergency 911 dispatchers indicated that Parrish was thrown about 10 to 15 feet from her vehicle when it rolled. Police said a tire that was ripped off Parrish’s truck after it struck the power pole hit a Dodge pickup truck that was following her Chevy.

Authorities said speed and alcohol are believed to be factors in the crash, which remains under investigation.
