State Police Say Fatal Motorcycle Crash is Still Under Investigation

“She crossed over the center line and hit the motorcyclist head on, so what the contributing factors were, we are still trying to determine that. That’s why it is still under investigation. We try to look at all different angles and different possibilities,” says Captain Eric Dayley, Idaho State Police. 
The fatal crash occurred when Joanne Christofferson, 29, was driving eastbound on US30 when she crossed the centerline into the westbound lane and crashed into a Harley Davidson driven by Staci Shryrock, 44, also of Pocatello. Shryrock was pronounced deceased at the crash site. Christofferson was taken to Portneuf Medical Center. As of Saturday, Christofferson was arrested and held at the Bannock County Jail. What every family needs to know about wrongful death claims: When someone dies as the result of an accident, family members must make many decisions, and a wrongful death claim often needs to be filed. Often a claim can be filed only by certain family members, and there are strict requirements and deadlines that must be met. It is critically important to speak with a wrongful death attorney to get information on a victim’s rights and options. Click here to learn more.
