Dallas police officer Amber Guyger was described as a "security guard" in a dispatch call to firefighters in the moments after she shot Bothem Jean in his own apartment even though she was in full police uniform.
That revelation, which can be heard in the above video, may explain why she had contacted Jean several times since moving into the apartment a month ago to complain about noise he was allegedly making, including a call on the day she killed hm, a detail brought to light Monday by an attorney for the victim's family.
And it may also explain the contentious exchange overheard by two sisters who live in a nearby apartment at the time of the shooting.
"Let me in, let me in," demanded a female voice while pounding on a door, followed by the sounds of gunshots.
"Oh my God, why did you do that?" a man's voice then said, probably Jean's final words.
And it would also explain why police have issued so many versions of the story, none of them adding up or making sense, all of them contradicting each other, blaming Jean in one way or another for his death.
In other words, it's beginning to look like Guyger had taken on the role of an overzealous security guard at her apartment complex, shooting and killing Jean over whatever noise he may or may not have been making in the apartment above her.
As far-fetched as that may sound, it's much more plausible than the three versions police have told us so far.
Police said that Guyger was returning home after working 12 to 15 hours, a number that increases with each revision to make us believe she was exhausted from keeping the public safe from evildoers.
But she also lives within walking distance of the police department, so it's not implausible for her to have been at home at any time during her shift.
All three versions state that Guyger killed Jean after returning home from work and confusing his fourth-floor apartment with her third-floor apartment, then confusing him for a burglar, which made her fear for her life.
The first version claimed she inserted her key in the keyhole but the door would not open, so he placed the items she was carrying down to continue struggling with the door, drawing Jean's attention inside, who opened the door and startled her, which was why she shot him.
But that version began falling apart when a photo surfaced showing a big, bright red doormat in front of his apartment when she had no such doormat in front of her apartment, which should have been an indicator she was at the wrong door.
Videos also surfaced showing residents from that complex opening doors with fob keys, which turn green or red depending on whether they are the right key or not, similar to a hotel room card key, so there was no need for her to struggle with the door because she would have immediately known she was at the wrong door.
The second version claimed that Jean had left the door unlocked, which was how Guyger was able to walk into the darkened apartment and see a silhouette of a man who refused to show her his hands, which she somehow was able to determine even though she was unable to determine she was in the wrong apartment.
But when Jean's family said he would never leave his door unlocked because he was very meticulous and orderly, they came out with the third version, claiming that Jean left the door ajar, enabling Guyger to walk into the darkened apartment, which was when she was startled by a silhouette of a man who refused her verbal commands, whatever they may have been, which was why she shot him.
Besides the dubious claim she could not tell she was in the wrong apartment after stepping inside it, the second and third claims are also dubious because the doors of those apartments are designed to close and lock automatically.
So it is highly unlikely Jean had left the door open or ajar. He would have had to have done it on purpose. And that is something most people won't do. Especially somebody as orderly and meticulous as Jean.
But that may change now that police have decided to interview witnesses other than Guyger, including the ones that overheard the conversation outside their door.
The affidavit also states that Guyger mistakenly drove up to the fourth floor parking level instead of the third floor parking level where she was supposed to park because the parking floors are supposed to correspond with the residential floors.
But a resident of the complex said that most spaces are first come, first serve with only a handful of reserved spots, which means she could be parking on any floor at any time and it should not cause her to enter the wrong apartment.
Police have been saying she was tired from working so many hours, which is why she parked in the wrong spot and why she entered the wrong apartment and why she couldn't tell she was in the wrong apartment even after walking inside.
But she was alert enough to shoot Guyger in the dark, striking him once in the chest.
And if it's true she was working so many hours, it's likely she was doing so willingly to milk the overtime as so many cops like to do.
And living a block away is convenient in case she needs a quick nap.
And that may explain the noise complaints because for all we know, she is a control freak who can't stand the sound of somebody walking in the apartment above her while she's trying to nap during the day.
After all, it's much easier to believe she killed Jean in a fit of rage than it is to believe she killed him in a state of oblivion.
