Among these four people, who killed the little girl?

After analysis, we can be sure that No. 2 is the murderer, because only No. 2 actually took a photo with the little girl, and the others were all photos taken with four people. Let’s talk about the fourth person first. Looking at the photo of him and the little girl, his arms are very thick, almost catching up with the little girl’s upper body, and the hand on the little girl’s shoulder is obviously out of proportion, so it’s p. Let’s look at the third person, his butt It feels like it's hanging in the air. This is because the original photo shows the person sitting on the ground, but the height is different from the height of the little girl's feet. If he puts his hands on the little girl's shoulders, the little girl won't be able to support his weight. , and then let’s talk about the first one, because there are two people in the photo who only have one hand, that is No. 1 and No. 2. Therefore, No. 1 and No. 2 have the same hands on their shoulders as in the photo of the little girl. , that is to say, one is real, and one is p. The position of the first boy is exactly the same as in the photo, but after flipping the picture, it is p. Why is it said to be p? One is if it is normal Why are the heights of the two people in the photo so different? Especially when the boy is older, he must be slightly taller than the girl if he squats, but this photo is so much lower, and the proportion of his arms is obvious when his hands reach his shoulders. It doesn’t fit, it feels longer, and the only one left is No. 2. Only he really took the photo with the little girl. No matter the expression, the direction of the gaze, or the height of the two people, it felt like they were taking the photo together. In addition, The height comparison of numbers 1, 3, and 4 in the group photo of four people is the same as that of the little girl. Only number 2 is different, so only number 2 is the real photo, and the others are all photoshopped from the group photo of four people. !
