Are we absolutely sure there wasn't a GoPro with the headlamp? According to the Google, you can mount a headlamp with a GoPro. That would explain the language in the SW about SP possibly recording the murder. Someone in an earlier thread said there definitely wasn't a GoPro, but I figured I'd ask again among the WS experts. Y'all are pretty amazing.
Interesting thought.....a GoPro can be viewed live, remotely, but only through a common wifi signal to a phone. Does the church have open wifi? Could someone in a car have watched it happen through the wifi signal as proof it was finished and also could have been directing the perp through a headset from what they were seeing live. Thus the half attempt to get into the door?
I wear a GoPro on a hat to film what I am seeing a lot when I fish or bike. You end up turning your head in weird ways instead of just moving your eyes to make sure the camera is seeing what you are seeing. Similar to how the perp looks in several frames.
Just something that popped into my head. FWIW
