It is not logical to take unique incidental examples of unusual suicides as a standard and Anna Oung was known to be in a psychotic state. Do you think all those gangsters in the 40s shot themselves twice in the back of the head too? Obviously no one ran Kathleen off the road or there would have been damage to her car. As I said I think that she was kidnapped in the city for some purpose and that happened to be the place where it went bad. Milwaukee has a known problem with kidnappings. They also have a known problem with slow investigation.
