Actually spoke to someone at the state level that works with someone involved with the investigation - apparently it was not a jumper left behind but operator error.... older bird cage style elevator with the typical manually operated accordion gate on the car and swing doors at each landing. Passenger was loading on something large like one of the mattresses or box springs that come in a box, she was not fully in the elevator but the hall door closed making up that circuit then the item she was loading made up the gate switch, a lower floor call was already in place, and being an older birdcage style car with a manual gate meant there were no open and close limits for the car gate, so once that gate switch was made up the car took off... again just what I was told by someone who knows the elevator portion of the investigation ended up finding out it was truly an accident.
