Damage to rear passenger fender- opinions wanted

It seems unlikely a trailer hitch that's in the center of a vehicle would hit the fender there in a parking lot. The vehicle with the hitch would have to come in at a 90 degree angle compared to the vehicle that was hit. I think it came from the other vehicles LF corner as it was backing up but what's on that vehicle to cause a cut like that I don't know. It's definitely a truck hitting a truck. Do you park near the complexes dumpster? (Trash truck)
