Police Commissioner Grant Stevens has seen his fair share of crash scenes but yesterday was one of the most horrific ones he had ever attended.
Shanahan was a passenger of the Holden SUV which was driven by her husband, who is also a retired police detective and is currently South Australia Police’s General Counsel. He escaped serious injuries and returned home to their two adult children.

Members of the public flooded the South Australia Police with messages, in particular, from victims of crime and domestic violence, a group Joanne worked tirelessly with.
“She was integral in the establishment of our multi-agent protection services, which has served so many victims of domestic violence,” Stevens said.
Mother of one, Tania McNeill, 53, was driving alone and also died in the crash. She was making deliveries for her family business.
A 20-year-old man in a third vehicle was taken to hospital with life-threatening injuries.
Investigations are still ongoing surrounding the events of the fatal crash, but excessive speed was a factor in the collision.
