"We're grateful for the quick and heroic response by law enforcement to save lives, including the life of a child. Our thoughts and prayers are with the victims, their loved ones, and the first responders who daily risk their lives for us all." The same day, the sheriff's office released an August 2018 photo of the suspect. Sgt. Jensen wrote in the media release Sunday the road at the scene was reopened at approximately 11 a.m. "Please drive carefully as investigators are still processing the crime scene," he said yesterday.
