Yep. Walking to the wrong classroom, apartment, hotel room, etc., can’t be uncommon.
Once I was given a key card to a hotel room that someone else was already sleeping in.
Another time, I was standing at a sink in a ladies’ restroom when a man walked in, saw me and stopped, looking shocked for a moment. Then he must’ve noticed the absence of urinals. We both burst into laughter.
I have no sympathy for this woman. But I can believe she walked to his apartment by mistake. Walking to his apartment by mistake wasn’t the crime. Shooting him was the crime.
If this was premeditated, why would she call 911 on herself and risk life in prison?
Doormat outside the victim’s apartment was bright red.
