From your link runfar - this investigation was so messed up:
"Many things that occurred that day were in violation or simply not done. Former longtime chief medical investigator Dr. Ross Zumwalt testified that neither the state Office of the Medical Investigator nor APD had considered Han’s bank statements, credit card records, medical records, cellphone records, the other prescription medications in her system, such as Ambien, or the contents of her laptop to determine a manner of death. They hadn’t tested the air in the house, the clear liquid in the glass or the plastic bag in the car; nor had they questioned the positioning of her body in the car."
