Package mystery

 There is a sign at the main gate to our complex that says "Don't leave packages by the gate." I got 2 deliveries this day, both left by the gate, as confirmed by the photo:

When I got home, the large package was by my front door and the small package was no where to be found. The mystery is not who took the small package, but rather, who moved the (very heavy) large package from inside the gate to outside my unit? Was it the person who took the small package???

P.S. Walmart sent a replacement for the missing item, and guess where the delivery was left...
