I did not see a gun in the video. At what point (time) in the video is her gun visible?
There’s a suggestive blur before he shoots, but in the abbreviated video it’s visible at 0:19 on the floor and highlighted at 0:21 next to her body. Looks like a modern autoloader with a flashlight. FWPD has put out full, unedited takes of the videos so it’s pretty clear it’s not a drop/plant gun either.
