UPDATE: Deadly Crashes Over Christmas Holiday

KHQ.COM - The autopsies on the occupants involved in the fatality crashes over the Christmas weekend on Salnave Rd. and Cedar Rd. were completed on Tuesday morning at the Spokane County Medical Examiner's Office.

In reference to the Salnave Rd collision, the driver of the 2004 Ford F-150 pickup has been identified as 28-year-old Derrick R. Wilson of Cheney.  Wilson's passenger was identified as 30-year-old Brett A. Schallock of Spokane.  Both men died due to blunt force trauma to the head.

Sheriff's traffic investigators have learned that both Wilson and Schallock had been drinking at a tavern on the north side of Spokane earlier in the evening. Investigators also obtained crash data from the Ford's powertrain control module (PCM) and discovered the pickup was traveling around 99 mph just seconds before crashing.

In reference to the Cedar Rd crash, the driver of the 2008 Chevrolet Avalanche has been identified as 45-year-old Bradley J. Updegrove of Deer Park. The cause of death was a fractured neck. Speed or weather conditions didn't appear to be factors in this collision. This particular vehicle has an airbag control module (ACM) that also records crash data similar to the Ford F-150. Investigators will be imaging this module with their crash data retrieval software later in the week to learn more about what the Chevy was doing moments before the crash.

Blood samples were taken from the vehicle occupants at the autopsies and will be sent to the state toxicology laboratory for analysis. The results will take about a month to get back and to learn whether or not or how much drugs or alcohol may have factored into the collisions.
