The browtine comparison is the key. It's obvious that pic's 1 & 2 are the same deer, based on the date/time stamp. The left browtine is clearly longer than the right in pics 3 & also pic 2. If you look closely in pic 1, you will notice that the left browtine does NOT end at that dark spot that is silhouetted against the right main beam. In that photo, it just happens that the left browtine is almost in perfect alignment with the right side G3. It even extends a little above the G3, and you can see a small "bump" that appears to be on the G3, but is actually the tip of the left side G1.
All that to say, all 3 pics are the same buck.
