The fact that the suspect was carrying what looks to me to be an empty (or at least mostly empty) duffel bag is interesting to me.
I'm not an avid hiker by any means, but I have gone on quite a few hikes and can't recall ever seeing someone carrying a duffel bag -- someone on a trail with a duffel bag would probably stand out. We know the suspect had a car since he was
last seen driving towards the park exit, so it's not as if he did not have somewhere to keep the bag before entering the trail. It seems the suspect at least wanted to conceal his identity considering he took the time to cover his license plate with duct/electrical tape (which IMO he probably did before driving to the park), so why carry a duffel bag on the trail when it will likely attract attention?
The duffel bag does not make sense to me
unless he was carrying it for a specific purpose -- perhaps to dispose of something or pick something up in the park?
