There are so many rumors of evidence. Whereby even if only one piece of that evidence ends up proven in court, the Police lady, could end up with a serious conviction. E.g. Murder.
If it is true that she complained about bad noise coming from that apartment, that day or in the last few days, running up to the incident.
If anyone else, especially multiple people, complained about bad noise, on the day of the incident or last few days.
Because it would be an amazing coincidence, and a significant motive, for her to confront him, and possibly argue with him, and end up killing him.
If it is true that witnesses heard her banging on the door and then shouting, just before the incident. Because that would contradict her story of going to the wrong apartment and thinking it was hers. Also it would rule out the door being ajar.
If the electronic door locks (and any CCTV evidence in that building), keep records, which contradict her version of events. E.g. She first went to her own apartment, or she didn't try her key in the lock etc.
Were the apartment lights already on and/or switched on prior to the incident. Is that information, available via CCTV and/or any computers involved ?
Probably no computers involved, but if the recent apartments have smart electricity meters, maybe the information was recorded ?
Was any friend suppose to be visiting the killed man and/or does the actual room door currently close automatically and/or does the electronic door lock, notice if it is ajar and record that fact in its memory ?
Apparently her story has changed at least once. Does those changes, make one suspicious of her activities, or can the changed story be believed in court ?
Could a person realistically go to the wrong room, given things like the very noticeable and somewhat large red rug, under the door of the apartment ?
Policeman are suppose to be sensitive to their surroundings and are specially trained and experienced, to notice things, so that they can detect criminal activities and report such activities to the courts.
Could she realistically have accidentally arrived at the wrong car park floor (4 rather than 3), is it a possible mistake to make ?
If such a mistake was made, how noticeable would it be ?
The other shooting she was involved with. Was she 100% in the right, or was there miscalculation and error on her part ? I don't know if the court would be allowed to consider that.
But my understanding is that the reality is that US Policemen, very rarely have to shoot someone dead or badly injure them, with their gun. Most can go their full career without ever having to fire their service gun in anger.
Yet she has used it twice, in the space of around 12 months. Can that be reasonable or is it a statistical anomaly ?
