Yeah it's pretty frustrating, but I appreciate everyone's willingness to help.
df4550's profile says he's from PA, and there is info online about him going to High School in PA, but gtguard sent his item to CA. Interesting discrepancy, but not too alarming, because according to df4550's social media profiles, he is in the Marine Corps. So he could be anywhere at this point. I tried googling around and finding family members/friends to reach out to, but it's hard to track down his exact relatives. A common last name in that area, it appears.
Sorry if this is too internet stalk-y!
