Maybe I’m just face-blind or being dense but the photos from the scene of the crime look like a different dude than the ginning hostel check in guy. The jackets and backpacks are different. Although people can have multiple jackets and backpacks. We don’t see much of the shooters face but the eyebrows look different. Although, people can pluck/shave eyebrows. I guess the happy hostel guy would have come forward and been like “WTF?” and “I have an alibi” if it wasn’t him?
Not really? Why is that interesting?
Like you said, it’s hard to not be on security cameras, and they only shared the video of the attack that had a couple of frames of the upper half of his face. So they are looking for someone with the upper half of their face.
